Due to the superior, custom tool steel used by PASS, coatings are normally not required. However, special applications may require the consideration of using coatings when a higher
production volume is needed or when special premature wear problems exist.
Three types of coatings work well for these applications:
1.) TIN-coating (Titanium-nitride)
The most obvious feature of this treatment is a golden color.
The hardness of the TIN-coating is 2400 HV.
The coating thickness is approx. 3.
2.) TICN-coating (Titanium-CarboNitride)
It has a darker gray appearance.
The hardness of a TiCN coating is 3000 HV.
The coating thickness is approx. 3.
3.) T-MAX-coating
The T-MAX-coating has a darker gray to a blackish colouring.
It is a 2-layer-coating:
- first layer (basic) = TICN
- second layer (cover) = patented coating
This special coating doesn't have an own hardness but have an excellent sliding feature. As a result, the basic layer takes over the increase of a higher production volume. The
cover layer takes over the decrease of the adhesive wear.
