Packed with illustrations! Understand the basics of hard thin film coating and quality control just by reading!
We are pleased to offer a set of three booklets, "Choosing the Right Coating Without Making Mistakes," Volumes 1, 2, and 3, from our company, which specializes in DLC coatings known for their excellent wear resistance and lubrication properties! In Volume 1, we provide an easy-to-understand explanation of the basics of coatings, including what coatings are, the types of coating materials, and actual coating methods. Volume 2 focuses on "Quality Control of Hard Thin Films," introducing fundamental knowledge and measurement methods for film thickness, hardness, and adhesion strength, including the "HRC indentation test method." In Volume 3, we present various test data comparing the friction coefficients of different metals and hard thin film materials, as well as comparisons of DLC friction coefficients based on combinations of sliding materials, all clearly summarized with diagrams and graphs. *You can read it immediately by downloading!

Company information
By adopting special sputtering and plasma CVD processes, we provide high-quality coatings with excellent adhesion even at low-temperature treatments below 180 degrees, along with high film thickness precision and outstanding tribological properties such as wear resistance, seizure resistance, and low friction coefficient, all based on abundant achievements and experience, with short delivery times. In particular, coatings from the Seltes brand, such as CrN-based coatings (Seltes X, N) as alternatives to Cr plating and Seltes DLC, which have excellent adhesion even under high surface pressure, are highly regarded in plastic molding molds, press molds, automotive parts, and high-precision sliding components. We also conduct various evaluations of metal surfaces and thin films, as well as defect analysis, using surface cleanliness measurement instruments like Corona Surf.
