作者对0.42%C和0.87%C的碳钢用销-环型磨损试验装置在白锭子油中进行了磨损试验。用光学和电子显微镜以及X射线和电子探针显微分析技术检验稳定的磨损过程中表面层的冶金组织、氧化、硬化情况和残留应力,并讨论了磨损速度与这些性质之间的关系。所得结论如下: (1)磨损情况可以分为两种型式:一种是滑动产生的轻微的磨损,另一种则是从剧烈转向轻微的磨损,这一剧烈磨损是由于咬合而造成的。(2)从剧烈转向轻微的磨损,在整个磨损表面上发生了连续的硬化层。(3)在连续的硬化层中观察到由于疲劳引起的微细裂纹和凹坑。(4)与在大气中比较,在白锭子油中这种碳钢的比磨损量都减少了10~2～10~4倍。而这个变化是随着滑动速度的减少而逐渐改变的。
The authors conducted a wear test on white spindle oil with a pin-to-ring wear test device for 0.42% C and 0.87% C carbon steel. The metallurgical structure, oxidation, hardening and residual stress of the surface layer during steady wear were examined using optical and electron microscopy and X-ray and electron probe microanalysis techniques. The relationship between the wear rate and these properties was also discussed. The conclusions are as follows: (1) Wear can be divided into two types: one is the slight wear caused by sliding, the other is from severe to slight wear, which is caused by bite. (2) From severe to slight wear, a continuous layer of hardened layers occurred throughout the worn surface. (3) Fine cracks and pits due to fatigue were observed in the continuous hardened layer. (4) Compared with the atmospheric air, the specific wear of the carbon steel in the white spindle oil is reduced by 10 to 2 to 10 to 4 times. And this change is with the reduction of sliding speed and gradually change.
