n-Al2O3-Fe复合镀层摩擦学特性研究

摩擦与磨损所造成的运动副配合间隙超标是装备零件更换的主要原因，造成了具大的经济损失，当前的采用镍等作为基体的纳米复合镀层不适用于零件修复。研究基体金属采用Fe的铁基纳米复合镀层，用于金属零件磨损后再修复具有非常重要的研究意义。在FeCl2溶液中加入纳米Al2O3，制成镀液，根据给定的工艺参数制备镀层，研究了镀层滑动、滚动、固定、半固定条件下摩擦学特性和与摩擦副配对的摩擦学特性。结果表明：镀层在滑动和固定磨料磨损条件下具有很高的耐磨性，在与摩擦副配对时，需要良好的磨合。研究发现，n-Al2O3-Fe具有非常优异的摩擦学性能，能满足装备机械零件磨损后修复的需要。

Study on Tribological Characteristic of n-Al_2O_3-Fe Compound Layer

The main cause of replacing equipment parts is friction and abrasion,it has case tremendous economic lost.N-based Ni compound plating layer is not fit for repairing metal parts.N-compound coating based Fe has the feature of effective,rapid and large depth.So it can do it well.FeCl2 plating liquid fixed with n-Al2O3 was adopted,in term of given technical process,so the coating can be acquired.Used the coating,glide,rolling,fixed,half fixed friction and frictional pairs tribological characteristics were studi...
