摘要
借助于电子显微镜，对不同成份的高铬耐磨堆焊金属的显微组织进行了对比分析。结果表明，堆焊层中高硬度的碳化物Cr7C3在α－Fe基体上呈粒状且均匀分布时，其耐磨性优于碳化物Cr7C3在γ－Fe基体上呈粗大板条状且分布不均匀的情况。
In this paper, the microstructure of high-chromium surfacing metals with different chemical composition are analyzied by means of electron microscope. The results indicate that when the carbides in surfacing metals are spheroidal and uniformly distributed at α-Fe matrix its abrasive wear resistance is better than coarse lath carbides are nonuiformly distributed at γ－Fe matrix
