プラズマイオンアシスト List of Products and Services

Utilizing plasma ion engineering, we provide functional DLC coatings for almost all materials. We have achieved DLC coatings on not only steel, SUS, and cemented carbide, but also on ceramics, various rubbers, plastics, and other organic materials. Our unique plasma ion injection and film formation technology allows for coating on submicron fine shapes, large equipment, inner surfaces of pipes, and deep grooves. Depending on the application, we propose customized specifications of DLC that meet customer needs, incorporating functions such as conductivity, low friction coefficient, barrier properties, release properties, and superlubricity, and we develop these in collaboration with our customers.

• Other metal materials

We have developed a conductive DLC film deposition device with the approval of NEDO, utilizing our unique plasma ion technology. Conductive DLC makes it possible to use general-purpose SUS materials for metal separators in fuel cells.

Our method allows for the deposition of DLC with low internal stress. As a result, thick DLC films can be deposited, which are resistant to most acids and alkalis. We can also deposit on complex shapes and the inner surfaces of pipes, which is difficult for other companies.

【Features】 - Our unique PIA film formation method allows for coating rubber, resin, and non-ferrous metals (such as aluminum, nickel, titanium, etc.) at room temperature, which was previously impossible. - It is possible to achieve a porous-free thick film DLC coating. - Functions can be added to DLC (such as water repellency, release properties, conductivity, etc.). * The photo shows the PIAD device that enables high-speed DLC coating on complex shapes at room temperature. - Film formation is possible from nano-imprint molds to long, large-area substrates.

Introducing the "Fuel Cell Separator DLC Coating."

• Surface treatment contract service

It is possible to increase the hardness and lifespan of molds and tools made of ultra-hard alloys by using nitrogen ions. Since this is not a coating, it does not change the shape of the product. Additionally, because no heaters are used, there is no deformation due to heat. Please feel free to contact us when facing severe usage conditions that cannot be resolved by various coatings. We have a proven track record in applications such as addressing wear on the inner surfaces of powder metallurgy molds under high pressure, or situations where there is a desire not to change the cutting edge shape of cutting tools used for processing high-hardness materials.
