为研究金属橡胶用选择性激光熔融(SLM)技术制备的316L不锈钢细丝在脂润滑条件下的摩擦磨损性能，探讨了不同载荷、不同摩擦速度以及F·v因子对SLM-316L细丝摩擦系数和磨损率的影响规律，利用扫描电镜观察细丝磨损表面形貌，利用能谱仪（EDS）检测磨损表面元素种类与含量，分析其磨损机制。结果表明：在脂润滑条件下，摩擦系数随着载荷的增大而减小，磨损率随载荷的增大呈先降后升的趋势。摩擦系数和磨损率均随摩擦速度的增大呈先升后降趋势。低载荷下SLM-316L细丝磨损机制主要为磨粒磨损和轻微的氧化磨损，较高载荷下氧化磨损加剧并伴随疲劳磨损。低摩擦速度下SLM-316L细丝磨损机制主要为疲劳磨损和氧化磨损，较高摩擦速度下氧化磨损减弱，以磨粒磨损为主。摩擦系数随F·v值的增大而减小，磨损率随F·v值的增大呈先升后降再升的变化趋势。因此用SLM-316L细丝制备的金属橡胶在脂润滑条件下最佳工作参数：F·v等于0.04 N·m·s-1，即载荷10 N、摩擦速度240 mm·min-1。
In order to study the friction and wear properties of 316L stainless steel filaments prepared by selective laser melting (SLM) technology for metal rubber under grease lubrication conditions, the friction coefficient and wear of SLM-316L filaments under different loads, different friction speeds and F·v factors were discussed. Use scanning electron microscope to observe the surface morphology of filaments after wear, use energy dispersive spectrometer (EDS) to detect the type and content of friction surface elements, and analyze the wear mechanism. The results show that under the condition of grease lubrication, the friction coefficient decreases with the increase of the load, and the wear rate first decreases and then increases with the increase of the load. The friction coefficient and wear rate both increase first and then decrease with the increase of friction speed. The wear mechanism of SLM-316L filaments under low load is mainly abrasive wear and slight oxidative wear. Under higher load, oxidative wear is aggravated and accompanied by fatigue wear. The wear mechanism of SLM-316L filaments at low friction speeds is mainly fatigue wear and oxidative wear. At higher friction speeds, oxidative wear weakens, and abrasive wear is dominant. The friction coefficient decreases with the increase of the F·v value, and the wear rate first rises, then decreases and then rises with the increase of the F·v value. Therefore, the best working parameters of the metal rubber prepared with SLM-316L filaments under grease lubrication conditions are when the F·v value is 0.04 N·m·s-1, that is, the load is 10 N and the friction speed is 240 mm·min-1.
