DYNA-BLUE can also be used as a substrate for PVD Coatings such as TiN, TiAN, CrN, CrWN, etc. DYNA-BLUE provides a hard 75+ HRC support layer below the surface of a PVD coating. Typically when the PVD coating wears off tool life drops off dramatically but with a hard DYNA-BLUE layer beneath the coating even when the coating is gone DYNA-BLUE still provides excellent tool life. Also galling and “Egg Shell” effect are eliminated!!!
