Preparation and Cutting Performance of YT15 Cemented Carbide Tools with Ti (C, N)/Al₂O₃ Composite Coating

Abstract:

The Ti (C, N)/Al₂O₃ composite coating was prepared on surface of YT15 cemented carbide by using electro-spark deposition process. The surface morphology, energy spectrum analysis and microhardness of the coating were investigated, and the cutting forces and wear resistance of the tools with and without Ti (C, N)/Al₂O₃ composite coating were studied by cutting tests. The results show that the microhardness of the YT15 cemented carbide with Ti (C, N)/Al₂O₃ composite coating increased 181Hv, and the coating tools had better wear resistance and lower cutting force.
