Effect of hot isostatic pressing nitrogen on the microstructure and properties of a Ti(C, N)-based cermet
چکیده انگلیسی
The high-temperature, high-pressure hot isostatic pressing technology was used for depositing hard coatings on Ti(C, N)-based cermets. The microstructure and properties of the sample were investigated using optical microscopy, scanning electron microscopy, X-ray diffraction, electron probe microanalysis, and microhardness tester. The results showed that the rich titanium and nitrogen in surface zone were induced by the heat treatment. The high nitrogen activity of the surface region was the driving force for outward transport of titanium and inward transport of tungsten in the cobalt binder. The toughness and hardness were improved and a hardness gradient was formed. It is the high-temperature, high-pressure N2 that enables closure of holes, thereby alleviating defects and prolonging tool life.
