金属表面喷涂层与适当后处理结合，是提高金属表面耐磨、耐蚀性的重要手段。本试验是对金属基体上喷涂Ni-Cr－Si－B粉末后分别进行三种不同方式的后处理—氧乙炔火焰重熔、钨极氩弧重熔及激光束重熔，用以考察不同的重熔方式对过渡层显微组织的影响。用金相显微镜对重熔层的组织进行了观察，用电子探针测定了重熔状态下熔层中各元素的分布曲线，并沿试样的横截面测定了显微硬度随熔层深度的变化曲线。
Metal surface spray coating and the appropriate combination of post-processing, is to improve the wear-resistant metal surface, an important means of corrosion resistance. In this experiment, three different ways of post-treatment of Ni-Cr-Si-B powder were carried out on the metal substrate - oxyacetylene flame remelting, TIG remelting and laser beam remelting to examine different Effect of Remelting Method on Microstructure of Transitional Layer. The microstructure of the remelted layer was observed with a metallographic microscope. The distribution curves of the elements in the remelted layer were measured by the electron probe. The microhardness of the remelted layer was measured along with the depth of the melted layer Curve.
