SurfTech 6020 coating is better known in the industry as TiN (gold coating).
TiN provides added tool life over uncoated metals with additional hardness and lubricity. While it is well known in the industry as a ‘standard’, we at SurfTech recommend our 4253 or 5300 for even greater wear and tool life over TiN. TiN can be added ‘on top of’ our other coatings for customers that require it for appearance purposes.
The industry standard coating has long been TiN (Titanium Nitride), is SurfTechs coatings equal or better?
Yes/both. Our SurfTech 4253 is better than TiN because it is a Multilayer coating system that allows us to fuse together the benefits of an ultra-hard coating materials like boron carbide with lubricous moly disulfide. This provides a hardness up to 2x that of TiN while lowering the coefficient of friction in half…(see SurfTech coating chart)
For customers that want to stick with TiN, we also offer it along with several other coating formulations.
What makes SurfTech coatings unique or different?
- Low temperatures (below 200 F) eliminates the risk of cobalt leaching and hydrogen embrittlement
- We coat up sharp edges with 2-4 microns which means post-process grinding, buffing and resharpening isn’t needed in our process…sharp in ~ sharp out ~
- We can coat ceramics, glass, even plastics…try that with others
- Our Multilayer coating system allows us to fuse together the benefits of ultra-hard coating materials like boron carbide with lubricous moly disulfide. This provides a hardness up to 2x that of TiN while lowering the coefficient of friction in half…(see SurfTech coating chart)
Many people say they PVD Coat, “…at low temperature…” is there a difference?
- Others call 850-900F low temperature… we think above the point of boiling water (210F) is high temperature J
- We believe low temperature is below 200F…this is where we coat
