Reaction Synthesis of TiC-Ni Composite Coating on Copper Substrate Using Electro-thermal Explosion Ultra-High Speed Spraying

摘要：

　　In this work,TiC-Ni coating was synthesized on copper substrate by electro-thermal explosion ultra-high speed spraying method at the discharge voltage of 26kV.Microstructure,phase structure,elemental distribution and microhardness of the coating were studied by means of scanning electron microscope in back-scatter-electron and secondary electron,energy-dispersive analysis X-ray spectroscopy,X-ray diffraction and Vickers hardness tester.The TiC-Ni coating,which exhibits no pores or cracks,consists of an irregular spheroidal TiC phase embedded in a nearly continuous Cu0.81Ni019 binder.TiC particles are uniformly distributed and the size of the TiC particle of the coating is less than 1.0 μm because of the solute trapping effect.The average hardness of the TiC-Ni coating is approximately 1200 HV0.3.
