针对深海推进器用机械密封在工况周期波动下磨损失效现象,在机械密封PV试验机上进行拟实工况测试,建立不同材质摩擦副配对在工况周期波动和定工况下的对照性试验,测试摩擦副实时摩擦系数、形貌演变、表面磨损等数据。试验结果表明:工况周期波动下的SSiC-M106K摩擦系数振幅频率高于恒定工况,且表面粗糙度由0.026μm上升至1.08μm,产生的磨粒对M106K表面造成二次磨损;另一方面,在3种不同材质的摩擦副配对中,SSiC-WC在工况周期波动下的摩擦系数最小且始终稳定在0.012~0.027范围。经SEM电镜测试后发现:以SSiC为动环的SSiC-WC摩擦副磨损程度较小,未出现犁沟效应,而SSiC-M106K表面出现明显磨痕,这是由于在滑动接触过程中磨料在石墨表面转移而导致磨损加剧。因此,SSiC-WC的摩擦配副更适应工况周期波动的服役环境。
