[Surface Treatment] Low Friction (Lubrication/Release) / High Friction (Anti-Slip) Coating
We perform surface treatment not only through thermal spraying but also through various methods that combine thermal spraying with additional techniques.
The friction coefficient of Teflon is very low (the dynamic friction coefficient is 0.04), but Teflon coatings alone are often weak against wear and cannot maintain their initial performance. The low-friction coatings developed by the Japan Foundry Technology Research Institute combine various coatings, including thermal spraying, to achieve strong wear resistance and excellent lubrication and release properties that can be maintained over a long period. Conversely, we also implement high-friction (anti-slip) coatings that control various surface roughness and hardness. 【Features】 ○ Low-friction (lubrication and release) coatings utilizing thermal spraying and Teflon coatings → By coating with low-friction materials without using Teflon, it is possible to apply coatings that combine hardness exceeding Hv1000 with low friction. ○ High-friction (anti-slip) coatings with controlled surface roughness and hardness → Responding to various slip prevention needs, such as preventing objects from slipping on rolls or preventing slipping for people and vehicle tires in the rain.

basic information
【Coating Examples】 [Low Friction Coating] ○ A coating that seeks release properties against dyes → Compared to regular Teflon coatings, it is resistant to wear, has solvent resistance, and reduces film peeling. → If only regular Teflon coatings are used for food-related machinery or industrial machinery, durability is improved. ○ Industrial sleeves that also require hardness and corrosion resistance → Typically, coatings such as hardened overlays or self-fluxing alloys were implemented, but a coating requiring even lower friction was needed. → With a hardness of Hv1000 or higher, the friction coefficient against SUJ2 is about half that of regular coatings. [High Friction Coating] ○ Applied to rolls to prevent slipping of transported or wound items → Surface roughness and hardness can be freely selected. ○ Anti-slip coating for industrial machinery used outdoors → Implemented to prevent slipping when vehicles' tires or people pass due to rain or snow. → Not only for outdoor use but also exhibits strong anti-slip effects against slips caused by oil indoors or graphite powder, etc. ● For more details, please contact us or download the catalog.
