Research on Microstructure and Properties of Ni60-WC Composite Coatings on Cr12MoV Steel Surface Prepared by Sintering Cladding AITranslate
Abstract AITranslate
Ni60-WC composite coatings were prepared on Cr12 MoV steel surface by sintering cladding of Ni60-WC alloy powder.The phase composition,microstructure,interfacial structure and cross-sectional hardness distribution of Ni60-WC composite coatings were analyzed by metallographic microscope,X-ray diffractometer and Rockwell hardness tester.The effects of sintering temperature,insulation time and heat treatment process on microstructure and properties of the composite coatings were studied.The results show that Ni60-WC composite coatings mainly consist of γ-Ni-based solid solution and hard phases such as WC,W2C,B6Fe23,BNi3 and FeNi.When sintering temperature is 1 050 ℃ and insulation time is 30 min,the composite coating is compact with few pores and good metallurgical bond at the interface.Heat treatment promotes the diffusion of alloying elements between the coating and the substrate.The hardness of the substrate and the coating is effectively improved also by heat treatment,and the hardness value of the coating is increased from 59 HRC to 65 HRC.
