TiCN

The TiCN coating has less internal stress, higher tenacity and good lubricant and wear risistance etc. It is porper to the occasion of requiring low coefficient of friction and high hardness. Because TiCN has lower coefficient of friction and higher hardness than TiN, the tools deposited TiCN is more proper to cut hard materials like stainless steel, titanium alloy and nickel alloy.The TiCN coating has better wear resistance and stability at high temperature. Using TiCN as main wear resistance coating of coated cutting tools can highly prolong the lifetime of cutting tools.

The TiCN coating is usually used on the cutting tools, forming tools and punching shears tools, that need high speed cutting, high speed feeding and the blades are often impacted. But we should pay attention to the material and surface condition of the substrates, for example: TiCN is not proper for the condition of high temperature, e.g. dry cutting of stainless steel.
