用表面机械研磨对低碳钢板材进行 面处理、经 X射线衍射及透射电镜分忻表明,处理后的样品上已形成了纳米结构表层.用往复式摩擦实验机研究了处理后样品的摩擦磨损性能.结果表明其磨擦系数较未处理样品明显降低,其磨损量在低载荷及中等载荷作用下也较未处理样品降低.磨痕形貌的扫描电镜观察表明、表面纳米化能减弱低碳钢的疲劳磨损效应,提高材料的摩擦磨损性能.
Surface mechanical grinding of low carbon steel sheet surface treatment, by X-ray diffraction and transmission electron microscopy Xin Xin showed that the treated sample has formed a nano-structure surface. The friction and wear properties of the treated samples were studied with a reciprocating friction tester. The results show that the coefficient of friction is significantly lower than that of the untreated sample, and the wear loss is lower than that of the untreated sample under low and medium loads. Scanning electron microscopy observation of wear scar morphology shows that the surface nano-technology can weaken the fatigue wear effect of mild steel and improve the friction and wear properties of the material.
