In 2012 we acquired the patent for the nanolayer blue coating based on AlTiN/TiN (patent no. 23538: Hard protective coatings with the ability to change their color).This is a nanolayer AlTiN-based coating, which is suitable for protection of cutting tools for machining of very hard (up to 62 HRC) and tough materials. The distinct blue color is the consequence of selective absorption and interference in the upper few nanolayers; it enables a much easier detection of tool wear.
