磨损腐蚀
fretting corrosion
mozhen fUShl靡振腐蚀(fretting Corrosion)两接触面间振动滑移引起的磨损和腐蚀介质的联合作用所产生的局部性金属腐性。该种腐蚀多发生在振动构件的机械结合处。可破坏材料接触面，使紧配合松动，甚至脱落。腐蚀产生的氧化物可导致局部应力，引起疲劳裂纹，甚至粘结。还可改变接触电阻，从而影响弱电流继电器的功能。产生该种腐蚀的机理有磨损一氧化和氧化一磨损两种。前种理论认为在受压的金属界面上，某些微小突起部分发生冷焊，然后在相对运动过程中，冷焊区局部断裂，形成很小的金属碎屑，因摩擦热又将其氧化。这个过程的反复进行，在界面上形成小坑或细槽，并积存氧化物碎屑。后种理论认为大多数金属表面都有一层氧化膜，某些微小突起部分的氧化膜在高压下破裂成碎片，暴露出的新鲜表面被重新氧化或冷焊，然后在相对运动过程中，使冷焊区或氧化膜局部破裂，摩擦热又将金属或金属碎片氧化，如此反复，使接触面受到损坏。由此看出摩振腐蚀产生的基本条件是接触面必须承受载荷;接触面间必须存在振动或反复的相对移动;接触面的载荷和相对运动足以使表面产生滑动或变形;存在氧气。 减少或防止摩振腐蚀的措施有:(l)合理设计，阻止接触面相对微动。(2)表面处理，采用润滑剂或电镀低熔点金属以降低接触面间摩擦系数，或表面渗氮、喷丸、冷加工、镀硬铬，以提高接触材料的硬度。(3)合理选材。 (!陈树俊{)
