In order to fulfill our dear customers’ demand , we have use below
coating types to make improvement on some of our mold part product
TiN (Titanium Nitride) PVD (Physical vapor deposition) Coating
TiN is the most economical and commonly used PVD wear resistant
coating and it has the following advantages.
- Excellent wear resistance
- Superb performance of lubrication
- Thermal stability for most cold work metal working applications
- High micro hardness up to 2.300 Vickers
Note: TIN is recommended to be used with lubricants, and it is not
applicable to stainless steel, nickel or copper applications
TiCN ( Titanium Carbon Nitride ) PVD coating
TICN can be widely applied to PVD coating on stainless steel ,
nickel and copper metals , and it has the following advantages:
- Higher hardness and lower coefficient of friction than that of TIN
coating, thus, it has extremely high wear resistance
- Improved performance of lubrication
- Extremely high micro hardness up to3.000 Vickers
Note: it’s suitable for stainless steel, nickel of copper
TiAlN (Titanium Aluminum Nitride) PVD Coating
Particularly suitable for application generating heat on surface,
TiAN can covert the aluminum constituent to aluminum oxide, which
provides an extra protection against shear stress and wear
resistance on cutting edges. TiAN has the following features.
- High thermal stability
- Extremely high micro hardness up to 3400 Vickers.
