以?0.3mm的316L不锈钢丝和ZL101为反应源,通过压铸和热处理工艺,得到不同反应程度的316L不锈钢丝增强铝基复合材料。通过扫描电镜、显微硬度计和摩擦磨损试验机对该复合材料进行分析。结果表明:经热处理后,压铸态的该复合材料中,316L丝材与铝基材间发生了反应,形成了条形的、呈放射状分布的金属间化合物,其硬度为459HV0.1,达到基体硬度(123HV0.1)的三倍以上;在载荷为10 N的干滑动磨损条件下,经525℃+1.5h处理后的复合材料,其耐磨性是铸态复合材料耐磨性的4倍。
With 316L stainless steel wire of 0.3mm and ZL101 as the reaction source, 316L stainless steel wire reinforced aluminum matrix composites with different reaction degree were obtained by die casting and heat treatment process. The composites were analyzed by scanning electron microscopy, microhardness tester and friction and wear tester. The results show that after the heat treatment, the 316L wire and aluminum substrate in the die-cast composite material react to form a strip-like, radially distributed intermetallic compound with a hardness of 459HV0.1, reaching the matrix Hardness (123HV0.1) more than three times; under the load of 10 N dry sliding wear conditions, after 525 ℃ + 1.5h treated composite material, the wear resistance of the as-cast composite wear resistance of 4 times .
