Yellowish-brown powder. TiCN has a lower friction coefficient and higher hardness than TiN. Titanium-titanium carbide coated tools are more suitable for cutting hard materials such as stainless steel, titanium alloy and nickel alloy, which are more wear resistant and high temperature stable. Improve the life of the tool. Nature: It has low internal stress, high toughness, good lubricity, high hardness and wear resistance. It is suitable for applications requiring low friction coefficient and high hardness.
