The results show that matrix is mainly tempered martensite under the condition of quenching at low temperature and tempering at 550 ℃; retained austenite content increases and martensite content relatively decreases along with the increase of quenching temperature, meanwhile, the wear resistance improves.

结果表明:550℃回火条件下,低温淬火时基体组织以回火马氏体为主,随着淬火温度升高,残余奥氏体含量升高,马氏体含量相对减少,而耐磨性随淬火温度升高逐渐升高;

Under a low load of 50-100 N, there was not apparent influence of microstructure on wear loss. With increasing the load, the microstructures markedly affected wear loss. The wear loss increased with increasing tempering temperature and reducing hardness.

在50-100N的低载荷下,不同回火组织的磨损失重变化不大,随着载荷增大,回火组织对磨损失重有显著影响,磨损失重随着回火温度的升高和硬度降低而增加。
