摘要

采用选择性激光熔化法（SLM）在H13表面熔化不同WC质量分数的WC/GH3536复合粉末。利用扫描电镜（SEM）和能谱仪（EDS）分析了界面缺陷、微观结构和成分扩散情况。结果表明：WC含量为30%的复合材料具有最佳的高温耐磨性，磨损率为3.27 mm3·N−1·mm−1；与H13相比，复合材料的高温耐磨性提高了37%。

Effect of WC mass fraction on the microstructure and frictional wear properties of WC/GH3536 matrix composites fabricated by selective laser melting

WC/GH3536 composite powders with different WC mass fractions were melted on the H13 surface by Selective Laser Melting (SLM). The defects, microstructure and component diffusion at the interface were also analyzed by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results show that the composite with 30 % WC content has the best high-temperature wear resistance with a wear rate of 3.27 mm³·N⁻¹·mm⁻¹. The high-temperature wear resistance of the composite is improved by 37 % compared to H13.
