探求在一定温度范围内２０号碳钢质量相对磨损量随金属壁面温度变化的规律。根据试验结果，经线性回归处理后，得到了磨损量随金属壁温的增加先下降后上升的函数关系式，同时得到了磨损量达到最小值时的临界温度。此外，还讨论了金属表面氧化膜对磨损的影响。图２参７
Explore the law of the relative wear amount of 20 # carbon steel with the metal wall temperature in a certain temperature range. According to the test results, after the linear regression treatment, the function of the wear amount increases first and then increases with the increase of the metal wall temperature, and the critical temperature at which the wear amount reaches the minimum value is obtained. In addition, the influence of metal surface oxide film on wear is also discussed. Figure 2 Reference 7
