摘要
在室温下,将45#钢盘-销摩擦副置于直流线圈产生的磁场中,研究直流磁场对45#钢干滑动摩擦磨损性能的影响。结果表明:与无磁场条件下的磨损量相比,磁场条件下磨损量明显较低,并且随着磁场强度的增加磨损量降低。微观分析表明,磁场条件下摩擦表面生成更多的氧化膜,在摩擦过程中,氧化磨损起主要作用;磁场方向的改变影响磨损率的大小。
The friction and wear characteristics of 45 steel pan against 45 steel pin under direct current magnetic field and at dry sliding friction and room temperature were studied.Results indicate that wear under the direct current magnetic field is much lower than that without magnetic field,the wear is reduced with increasing the magnetic density.The results of microscope anlysis show the more oxide-protective film is formed at friction surface under the direct current magnetic field during the course of frictio...
