We will exhibit at the Tokyo Metropolitan Industrial Technology Research Institute, INNOVESTA.

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!
