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."
