The keyword in the Tetsuya Suzuki Laboratory of the Department of Mechanical Engineering at Keio University is ''nanomaterials''. The researchers in the Suzuki Lab are working to develop high-performance thin-film materials and to analyze such materials at the atomic level. In particular, Diamond-like Carbon, or DLC for short, is the main target. The researchers improve the DLC films and apply them in a variety of fields.
Seavac has been researching the conventional coating technologies using TiN, Ti-Al, and CrN, and developed ZERO-I, a new coating that combines the advantages of all three.
"The hardness is about 3,500 HV. This coating is heat-resistant to over 1,000 degrees. Conventional Ti-Al coatings were heat-resistant to nearly 900 degrees, but this coating has even better heat resistance, and hardness as well."
