摘要
利用半导体激光对AerMet100钢表面进行熔凝处理,研究了激光熔凝对材料结构、耐腐蚀性能以及耐磨损性能的影响。结果表明,通过激光熔凝可在AerMet100钢表面获得冶金质量良好、无裂纹的熔凝层;在750~1650 W功率范围内, 随着激光功率的增大, 熔凝层的厚度增大,熔凝层的硬度、耐腐蚀性及耐磨性均提高;当激光功率为1650 W时,其硬度、耐蚀性以及耐磨性达到最优;经过激光熔凝处理后,AerMet100钢未产生明显的物相改变,熔凝态中奥氏体含量减少,马氏体含量增加。
Abstract
The surface of AerMet100 steel is treated by semiconductor laser melting, and the influences of laser melting on microstructure, corrosion resistance and wear resistance of materials are investigated. The results indicate that the melting layer with a good metallurgical quality and without cracks can be obtained by laser melting. In the power range of 750-1650 W, the thickness, hardness, corrosion resistance and wear resistance of the melting layer increase with the increase of laser power. When the laser power is 1650 W, the hardness, corrosion resistance and wear resistance of the melting layer are optimal. The phase of AerMet100 steel does not change significantly after laser melting, but the austenite content decreases and the martensite content increases.
