一概述根据国内外一些文献记载,铜铅轴承镀了铅锡合金后,在使用中可以大大地缩短走合时间,避免轴承受酸的侵蚀,并增加耐磨性及延长轴承的使用寿命。再以我厂制造的铜铅轴承与美国的GM-71轴承(它表面镀有铅锡合金),在使用的过程中比较起来,在某些质量上还没有赶上它;例如耐磨性不够,容易被酸所侵蚀,以及在油内经常发现有铜沫子等缺点。为了要赶上GM-71轴承,我们试验室决定进行这项试验。经过多方面搜集有关镀铅锡的国内外文献,准备开始试验。但目前国内生产的轴承尚未采用这种电镀方法,所以在直接
According to a number of domestic and foreign literature records, copper-lead bearing plated with lead-tin alloy, the use can greatly reduce the walking time, to avoid corrosion of the bearing by the acid and increase wear resistance and extend the service life of bearings. Then the copper-lead bearing manufactured by our factory and American GM-71 bearing (its surface is coated with pewter) are not matched in some quality during the using process; for example, the wear resistance is not enough , Easily eroded by acids, and often found in the oil, such as copper foam shortcomings. In order to catch up with GM-71 bearings, our laboratory decided to carry out this test. After extensive collection of domestic and foreign literature on tin-plated tin, ready to begin the experiment. However, the current domestic production of bearings has not yet adopted this plating method, so in direct
