【摘要】 系统地研究了球墨铸铁QT60-2激光相变硬化层的摩擦磨损特性,并对磨损机理进行了探讨。结果表明,激光相变硬化层具有很高的表面强度、硬度,与高频感应淬火表面相比,其耐磨性更高,摩擦磨损特性更为优异。更多还原

【Abstract】 In this paper, the tribology and wear characteristics and wear mechanism of laser transformation hardened spheroidal cast iron QT60-2 are systematically investigated by means of wear tests. The results show that because laser treatment increases surface strength and hardness notably, the tribology and wear characteristics are greatly improved compared with those of induction hardened surface.更多还原
