仿生非光滑表面磨损机理的试验研究

为研究具有不同仿生非光滑表面特征试件的磨损机理,通过加工几种具有非光滑表面形态特征的圆形45#钢试件,利用正交试验方法设计耐磨性试验方案,在国产MM200型摩擦磨损试验机上进行试验.试验结果表明,在相同试验条件下,时间、负荷、速度、形态和分布对耐磨性均有影响,并且耐磨性按照凹坑、凸包、波纹、鳞片形态递减;通过分析磨损后非光滑形态表面的形貌及磨屑的图像,得出非光滑表面形态的磨损机理是磨料磨损,并且其磨损机制是微观切削.

Experiment research on wear mechanism with bionic non-smoothed surface

function of According to the investigation of bionics, the non-smoothed topography of some biology had the reducing soil adhesion and sliding resistance, and wears well. To investigate the wear mechanism time, load, speed and distribution all have influence on the wear resistance in the same experimental conditions, and the influence on wear resistance decreases according to the topography, such as concave, convex, ripple and scale. Through the analysis of the image of the grind article and the topography of non-smoothed surface, we can deduce the result that the wear mechanism was abrasive wear, and the abrasion mechanism was microcosmic-cutting.
