摘　　要：表面微孔织构化与润滑剂结合的制备技术能够有效地降低摩擦和延长工件的使用寿命。为此,研究了低成本、高效率的电解加工微孔表面织构化与MoS2干膜润滑剂的结合技术,并分析了其摩擦性能、磨痕表面及探讨微孔中润滑剂释放机理。结果表明,用电解技术加工微孔使表面织构化再填充干膜润滑剂是制备长寿命及低摩擦面的有效方法;摩擦面成膜的原因是表面织构化微孔中润滑剂的释放分3个步骤进行:即接触挤出,摩擦带至微孔前方,摩擦辅展成膜,润滑剂在摩擦副上成膜是降低摩擦系数的主要原因。Porous surface texturing technology with low cost and high efficiency based on electrochemical machining was combined with bonded solid lubricant of MoS2.The tribological behavior,wear scar morphology and mechanism for lubricant to release from the micro-pores were discussed.Results show that when the porous surface texturing technology is combined with bonded solid lubricating technology,the friction can be significantly reduced,and the service life of the metal workpieces can be greatly extended.Lubricant filled in the micro-pores of the textured metal surface could be released by three processes.Low friction coefficient was attributed to the film-forming process of lubricant on the friction pair.
