ART对45钢表面改性的研究

A Study of the Effect of ART Reagent on Surface Modification of 45 Steel

运用改装的摩擦实验机对45钢——灰铸铁摩擦副做旋转对磨实验,探索ART对45钢摩擦副表面改性的机理和耐磨规律。实验结果表明,磨损试样表面有大量小质点镶嵌,微区亦增添了来自矿物粉体中的元素;显微硬度明显提高,粗糙度显著降低。ART起到了良好的减摩耐磨效果。

The effect of ART reagent on the frication performance of 45 steel/cast iron pair is studied by using an improved friction apparatus. The ART reagent is added to the pair, and then the friction experiment is carried out at constant load and velocity under air condition. Emphases are mainly put on the mechanisms of surface modification and abrasion - resistant rule. Investigation by microscope indicates that many particles, such as the elements of ART reagent, are embedded into the surface. The micro - penetration hardness and surface roughness are gready increased and decreased respectively, which demonstrates the pronounced abrasion - resistant effects of ART reagent.
