Abstract
Disclosed herein is a method for coating carbide substrates using nanostructured and a non-nanostructured layers. The coatings can be produced by the addition of a refining agent flow, particular hydrogen chloride gas, during deposition, and can be produced as multiple individual titanium and titanium-based nanostructured layers varying functional materials. The combination of a nanostructured layers and non-nanostructured layers can produce a cutting tool insert that exhibits longer usage life. In addition, pre-treating the substrate with a mixture of compressed air and abrasive medium prior to coating the substrate and post-treating the coated substrate with a mixture of water and an abrasive can further enhance the wear resistance and life of the cutting tool.
