Abstract
Ti(C,N) ceramic materail plays an important role in the field of material processing due to their good mechanical properties and thermal stability. In this experiment, Ti(C,N) powders were successfully prepared by solvothermal and high-temperature calcining method, using TiOSO4 and C3H6N6 as raw material, and n-propanol and ethylene glycol as solvents. The microstructure of Ti(C,N) powders were characterized by X-ray diffraction and field emission scanning electron microscope, and their hardness were tested by vickers microhardness tester. The microstructure and mechanical properties of Ti(C,N) powders using two different solvents were investigated comparatively. Ti(C,N) powders prepared using n-propanol with a size of about 20–30 μm can reach the maximum hardness of 660 HV after sintering. Ti(C,N) powders prepared using ethylene glycol with size range of 3 μm to 5 μm come up to the maximum hardness of 889 HV. The different mechanism of solvents in preparation of Ti(C,N) ceramic material was discussed.
