英文摘要	The mixture of Ni, Co, Cr, Al, Y powders were prepared by mechanical mixing for 4 h with the ratio of 4:2:1.5:1:0.03 of Ni, Co, Cr, Al, and Y, and the deposited mixed powder coating with a thickness of 160 μm was prepared on the 310S stainless steel substrate by using the low-pressure cold spray equipment (GDU-3-15). The sample was placed into a vacuum tube furnace (TL1700) for thermal diffusion treatment. The microstructure, phase composition and microhardness of in-situ synthesis NiCoCrAlY alloy coatings were analyzed by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffractometry (XRD) and microhardness tester, etc. The results show that the mixed powder coating of Ni, Co, Cr, Al, Y prepared by the cold spraying is mainly composed of simple elements. However, the diffusion reaction of the elements occurs in the coating after vacuum diffusion at 1100 for 4 h. In the meantime, there is a diffusion phenomenon between the coating and the substrate, which forms an obvious metallurgical bond. Oxidation experiments show that the NiCoCrAlY coating of in-situ synthesis exhibits significantly lower oxidation mass gain than the pure substrate, which can protects the substrate from rapid oxidation effectively. © 2020, Science Press.
