．Good thermal stability
．Color of TiN : Golden yellow
．The hardness of TiN:HV2200
．Heat-resisting temperature of TiN : 500°C
．Friction coefficient of TiN : 0.4
．Increase the surface hardness： Covered TiN thin film tool steel, mould steel or hard alloy tool making use of PVD, can improve by 3-5 times of hardness of surface , reduce the wearing and tearing amount of the tool.
．Reduce the friction coefficient： Covered TiN thin film use of PVD, can avoid mould surface wear loss, stuck, scratched, etc, improve the precision of the products, reduce the mould consume and lengthen the life-span of the mould.
．Improve the quality of the products： Covered TiN thin film use of PVD, can improve the wear-resisting and heat-damage characteristic, process the speed, promote yield.
