Abstract

Abstract: NiCr/Cr₃C₂ composite powder was prepared by chemical and metallurgical coating, solid state alloying and spray granulation technology, and the NiCr/Cr₃C₂composite coating was prepared by atmospheric plasma spraying technology (APS). The microstructure of both the powder and the coating, as well as the microhardness, tensile strength and oxidation property of the coating were studied by using SEM, microhardness tester, universal mechanical tester and muffle furnace. The results show that the coating has a typical layered structure with excellent tensile strength (27.4±5) MPa. The microhardness of the coating is about 850 HV0.2, which is 2.7 times of that of bonding layer. The fracture of the coating is a typical brittle fracture, and occurs between the layers in the coating. The oxidation kinetics curve of the coating at 850 ℃ basically conforms to the parabola law, and the oxide film is produced on the surface of the coating, and will fall off during the oxidation process. At the same time, the segregation phenomenon appears in the coating, and the metal Cr is precipitated.

Key words: NiCr/Cr₃C₂ composite coating, mechanical properties, oxidation property, atmospheric plasma spraying
