Research on spraying surface modification coating of magnesium alloy plasma cleaner
Research on spraying surface modification coating of magnesium alloy plasma cleaner: Magnesium alloys have low density, high specific strength and specific stiffness, and have extremely important application value and broad application prospects in aerospace, transportation, 3C products (communication and computing) and other industries. In addition, magnesium alloy also has good biocompatibility, mechanical compatibility and degradability as a new type of biomedical implant material and has also received extensive attention. Although magnesium alloy has outstanding advantages, it has low wear resistance and poor corrosion resistance, which limits its application to a certain extent. Therefore, improving the corrosion resistance and wear resistance of magnesium alloys under different working conditions is a problem that must be solved to expand its application. The surface modification technology of plasma cleaners can increase the surface hardness, improve corrosion resistance, and enhance wear resistance by adjusting the composition and structure of the modified surface without affecting the strength of the material. Appropriate surface modification treatment of magnesium alloys is of great significance for exerting the performance advantages of magnesium alloys. Plasma cleaning machine spraying technology has the advantages of high productivity, fine coating structure, high bonding strength with substrate, low porosity, wide sources of spraying materials, and low cost, making it suitable for traditional fields such as wear-resistant coatings and corrosion-resistant coatings. The application is more extensive. Due to the differences in physical and chemical properties between the magnesium alloy substrate and the ceramic coating, residual stresses will be generated during the preparation of the coating, which will reduce the bonding strength between the substrate coatings and affect the overall performance. The metal/ceramic gradient coating sprayed by the plasma cleaner uses the metal phase as the transition layer and the ceramic phase as the surface layer, or as the thickness of the coating increases, the content of the ceramic phase gradually increases and the content of the metal phase decreases accordingly, which is a good solution. The problem of the mismatch of metal and ceramic properties. It greatly reduces or eliminates the stress in the coating and improves the bonding strength between the coating and the substrate. Plasma cleaner spraying technology prepares modified coatings on the surface of magnesium alloys, which greatly improves the surface hardness, wear resistance and corrosion resistance of magnesium alloys, and expands the application range of magnesium alloys.

What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces
What role does atmospheric plasma cleaning equipment play in the production of lithium battery pole pieces: When it comes to automotive lithium batteries, I believe everyone is no longer unfamiliar with them. The production process of automotive lithium battery pole pieces is more complicated, including slurry preparation, slurry coating, pole piece rolling, pole piece slitting and pole piece drying. It is a relatively new process to use atmospheric plasma cleaning equipment to process the pole pieces before coating. Therefore, what role does atmospheric plasma cleaning equipment play in the manufacturing process of lithium battery positive and negative plates? How does this help the product? The positive and negative electrode materials of the lithium battery are coated on the metal film to make the positive and negative electrodes of the automobile power lithium battery. Before the electrode material is coated, the metal film must be cleaned to improve the coating effect. The material of the metal film is generally aluminum foil or copper foil. In the past, the cleaning is done by wet processing. Even if the surface is cleaned with ethanol and other solutions, this cleaning method is likely to cause invisible damage to the lithium battery and other components. Will produce some residue. Due to these shortcomings, in the subsequent manufacturing process, the dry surface treatment method of atmospheric plasma cleaning equipment is gradually adopted. It can not only remove organic matter, make the surface of the film rough, improve the wettability of the metal film surface, but also improve the coating. The uniformity of the layer is conducive to improving thermal stability, safety and reliability. If you have any questions about the purchase or use of the equipment, please feel free to inquire.

The application of plasma cleaning machine (surface treatment machine) on fuel cell
The application of plasma cleaning machine (surface treatment machine) on fuel cell: Fuel Cell (FuelCell) can directly convert the chemical energy stored in fuel and oxidant into electrical energy. It is highly efficient, environmentally friendly and reliable, and is considered to be an effective and sustainable power generation technology in the 21st century. Among various fuel cells, Renewable Fuel Cell (RFC) is a medium-to-high energy energy storage system, which is mainly composed of two parts: water electrolysis cell and fuel cell. Water electrolysis generates hydrogen and oxygen through water cell electrolysis, and then passes through The electrical energy generated by the fuel cell converts hydrogen and oxygen into water. This process is characterized by recyclable and renewable energy. Renewable fuel cells are currently mainly used in energy storage hybrid systems and portable energy systems for spacecraft and spacecraft. Proton exchange membrane fuel cell (PEMFC) is also a typical proton exchange membrane fuel cell. It has the advantages of fast starting, long life and large specific power. It is especially suitable for mobile power sources and various portable power sources. It is an electric vehicle and other transportation tools. The ideal power supply. The development of renewable fuel cells and proton exchange membrane fuel cells is an important part of the development of new energy technologies. Conventional PEMFC chips mainly include thin-film electrodes and bipolar plates. A core component of the bipolar plate battery. Its functions are as follows: (1) Separate oxidizer and reducing agent; (2) Collect current for cooling the battery system; (3) Provide flow channels for reaction gas and water; (4) Support the membrane electrode. Therefore, the ideal bipolar plate material must be a good electrical and heat conductor with good air resistance, good corrosion resistance, low density, high strength, and easy processing and forming. The electrode plates of some batteries are plated on metal strips with positive and negative electrode materials. When the metal strips are plated on the electrode materials, the metal strips need to be cleaned and treated effectively with a plasma cleaning machine (surface treatment machine). Plasma cleaning is a kind of dry cleaning, which mainly relies on the activation of reactive ions in plasma to remove stains. The invention can effectively remove dirt, dust, etc. in the battery, prepares for pre-welding of the battery, and reduces defective products. In order to prevent battery safety accidents, it is usually necessary to externally treat the battery core to insulate, prevent short circuits, protect circuits, and prevent scratches. It can clean the end plate of the insulating board, surface dirt, surface roughness, and enhance the adhesion and adhesiveness. Several functions of plasma active particles: enhancing effects, such as bonding, bonding, welding, coating, and de-glueing.

The application of plasma cleaning technology in the cleaning treatment of photocathode accessories
The application of plasma cleaning technology in the cleaning treatment of photocathode accessories: In addition to the super-cleaning function, the plasma cleaner can also change the surface properties of certain materials under certain conditions as needed. Plasma acts on the surface of the material to recombine the chemical bonds of surface molecules and form new surface characteristics. For some special-purpose materials, the glow discharge of the plasma cleaner in the ultra-cleaning process enhances the adhesion, compatibility and wettability of these materials. Therefore, plasma cleaning, as a new type of cleaning technology, will be widely used in the fields of optics, optoelectronics, materials science, biomedicine, microfluidics, etc. Vacuum optoelectronic devices represented by low-light image intensifiers are widely used in national defense, scientific research and other industries, and are highly valued in China. The low-light-level image intensifier uses a photocathode to generate corresponding photoelectron images under the excitation of input photons from the scene, thereby converting weak or invisible radiation images into electronic images. In the ultra-high vacuum tube, the electronic optical system exerts great influence on the photoelectrons. A strong electric field is focused by an electron optical lens (or through a microchannel plate electron multiplying method), bombarding the phosphor screen with high-energy electrons to emit light, realizing the multiple increase of incident light energy, thereby producing the corresponding photon image imaging visible to the human eye Device. The low-light image intensifier is a vacuum photoelectric imaging device. Its production and manufacturing process is complex and diverse. Its production and manufacturing show two major characteristics: ultra-high vacuum, ultra-high cleanliness, especially the removal of hydrocarbons and hydrogen pollution. The stability of it is very important. Therefore, the device has very high cleanliness requirements for parts, accessories and semi-finished components in the process of circulation. Take the auxiliary parts used in the manufacture of photocathodes of image intensifiers: antimony base base and single tube base as examples. These two auxiliary parts are the main tools in the photocathode manufacturing process. The insulation performance of the ceramic terminal directly affects the photocathode. Manufacturing quality of production. The structure of the antimony base seat and the single tube seat is compact, the ceramic terminals are densely distributed, and the groove space at the metal rod is narrow. It is very difficult to scrub with tools. Previously, chemical immersion (RBS cleaning agent) and ultrasonic cleaning methods were used for the antimony base seat and single tube seat with poor insulation performance of the ceramic terminal. These cleaning methods were used to treat the antimony base seat and single tube seat with poor insulation performance of the ceramic terminal. The socket is cleaned. Although the insulation performance of the ceramic terminal of the antimony base has been improved to a certain extent, after a short period of use, excessive leakage current of the ceramic terminal will occur repeatedly, which is manifested as incomplete cleaning. The application of this method of cleaning makes the cleaning frequency of the antimony base seat and the single tube seat too high, and the frequency of use is low. At the same time, the use cost is increased, and the environmental pollution is also increased. Plasma cleaning technology is used to clean antimony base holders and single-tube holders with poor insulation performance of current ceramic terminals. When cleaning with a plasma cleaner, the entire quartz cavity of the plasma cleaner is filled with plasma, and any part of the workpiece, including small grooves, slits, and micropores that cannot be cleaned by ordinary cleaning methods, can be completely The cleanliness. At the same time, the use of plasma cleaning can fundamentally improve the insulation performance of the ceramic terminal, extend the life cycle of the antimony base seat and the single tube seat, improve production efficiency, reduce production costs, and reduce environmental pollution. Fully understand the application of new cleaning technology in the cleaning treatment of photocathode accessories, innovate the original cleaning method, improve the cleaning effect of the image intensifier accessories, and improve the product process yield and work efficiency.
