COATING TECHNOLOGY
VIOLET Coating
(Al,Ti)N coating, excellent adhesion strength for HSS tools.
Violet coating is the name of the technology of successfully applying a Miracle type coating to HSS substrate tools. Mitsubishi’s unique technology of applying (Al,Ti)N coating at the low temperatures required for HSS substrates, means that Violet coating has the same level of adhesion strength as Miracle coating. Additionally high film hardness and excellent oxidation resistance properties have also been realised.
