【Abstract】 Nitrogen low implantation significantly improves the friction and wear properties of GCr15 steel. Through an analogue spindle sliding test of arc-ring, the modification mechanism for the improvement of wear resistance of analogue spindle via ion implantation is analysed combining with a variety of surface analytical techniques such as TEM, SEM, XPS and AES. The test results show that nitrogen implantation has remarkable effect on the increase of spindle life. Several valuable implantation parameters are predicated by the orthogonal experiment.更多还原
