Abstract

Abstract: Some high chromium alloy casting infiltration composite layers with various vanadium contents were prepared on the surface of ZG45 steel by vaccum evaporative pattern casting process. Effect of different vanadium contents on microstructure of the layers was studied by using scanning electron microscopy (SEM), energy spectrometer (EDS)and X-ray diffraction (XRD), while that on the hardness and wear resistance was researched by using Rockwell hardness tester and the impact wear experiment machine. The results show that the structure of the casting infiltration layer is mainly composed of α-Fe and α-Fe+M₇C₃+VC eutectic structure. The alloying elements in the transition layer are distributed in gradient, and C, Cr, V elements are diffused from the casting infiltration layer to the matrix. The distribution of C, Cr, V elements coincide with the distribution of carbides. With the increase of vanadium content, the grain is gradually refined, the amount of eutectic carbides is gradually increased, the amount of VC is also increased, and the hardness and wear resistance of the casting infiltration layer is improved. After heat treatment, a large amount of secondary carbides is precipitated. With the increase of V content in the casting infiltration layer, the secondary hardening effect is significantly improved.

Key words: high chromium alloy casting infiltration layer, microstructure and properties, vanadium content, secondary carbides
