摘要

在27SiMn钢表面通过预置送粉方法得到了激光熔覆层，并对熔覆层进行了热处理。分析了热处理前后试样的显微组织、相结构、拉伸性能、断口形貌和显微硬度，获得了较优的热处理工艺参数。结果表明，热处理工艺可细化熔覆层的晶粒，使熔覆层的显微组织更加致密；热处理工艺可以改善材料的塑性和韧性，增大材料的抗拉强度，减小材料的显微硬度。在最优热处理工艺下，试样的晶粒均匀、细小且拉伸性能优异。

Abstract

The laser cladding layers on the 27SiMn steel surface are obtained by the preset powder feeding method, and the heat treatment to these cladding layers is also conducted. The microstructures, phase structures, tensile properties, fracture morphologies and microhardness specimens before and after heat treatment are investigated, and the better heat treatment process parameters are obtained. The results show that the heat treatment process can refine the grain size of cladding layers, which makes microstructures denser. The heat treatment process can improve the plasticity and toughness, which enhances the tensile strength and reduces the microhardness of materials. Under the optimal heat treatment process, the grains of specimens are refined and homogeneous, and the tensile property is superior.
