GCr15钢的摩擦温度与磨损的关系

THE RELATIONSHIP BETWEEN THE FRICTIONAL TEMPERATURE AND WEAR OF STEEL GCr15

研究了在不同正向载荷和滑动速度的干滑动条件下,GCr15钢的磨损体积和摩擦表面温度的关系。结果表明,随着正向载荷和滑动速度的增加,钢的磨损体积、磨损率和摩擦表面温度均增加。在试验的基础上给出了正向载荷与滑动速度的乘积(PV)与磨损,摩擦表面温度的回归关系式和摩擦表面温度与磨损的回归关系式。并指出当PV值为100N·m·s^(-1)时磨损急剧增加,而此时所对应的摩擦表面温度均为200℃。

The relationship between the frictional temperature and wear volume was studied under dry sliding at various normal loads and sliding speeds. The results indicate that the wear volume, wear rate and frictional temperature increase with incressing normal load and sliding speed. On the basis of the experimental results, regression formulae involvingthe PV value, fractional temperature and wear were obtained. When the PV value is about 100 N·m/s, the wear volume increases severely, and the corresponding frictional temperature is about 200℃.
