DLC coating has been achieved not only on steel, SUS, and cemented carbide, but also on ceramics, various rubbers, plastics, and other organic materials.
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.

Applications/Examples of results
【Technical Features - Example】 ■ Film formation on various rubbers is possible through room temperature coating [Improvement of slip properties for O-rings, squeegees, suction pads, etc.] ■ Low-temperature coating tailored to the characteristics of the equipment does not compromise the strength and internal stress of materials such as aluminum and nickel electroforming. ■ Inner surface coating of pipes (with an aspect ratio of opening and length greater than 5 times). ■ Uniform film on submicron fine shapes and improved release properties for nano molds using highly water-repellent DLC. ■ Application of conductive DLC to prevent adhesion of measurement terminals, secondary battery current collectors, and PEFC separators. 'Examples of Coatable Materials' Non-ferrous metals: Aluminum, Nickel, Nickel plating, Titanium, Cr plating, Cemented carbide Rubber and resin: NBR, CR, Silicone rubber, EPDM, FKM, Epoxy, CFRP, Nylon, etc. Ceramics: Alumina, SiN, SiC, SiO2, Zirconia, Borosilicate glass ■ Ion Treatment By performing ion treatment directly on the equipment instead of coating, improvements in hardness, release properties, hydrophilicity, antibacterial properties, etc., can be achieved.
