Study on the Microstructures and Wear Resistance of ZG30Cr steel surface layer

摘要

In this paper, the WC and high-Cr Cast Iron layer were obtained on the surface of ZG30Cr steel by casting-penetrating process, the organization and wear properties of penetrating layer were studied.The results show that the layer is dense, without pores, slag and other defects, the penetrating layer and substrate are metallurgical bonding. When 30 %WC and 70 % Cr-Fe with 100 ～120 mesh are added to permeability agent, the penetrating layer has the best wear resistance, is 6.8 times the matrix materials.
