摘要:

淬硬轴承钢恶劣的硬车加工性能显著降低了工件表面完整性,导致淬硬轴承钢摩擦磨损性能较差。基于电脉冲辅助切削技术开展了电脉冲辅助淬硬轴承钢的硬车实验,研究了其表面完整性和表面耐磨性。研究结果表明,相比于传统硬车淬硬轴承钢,电脉冲辅助硬车淬硬轴承钢工件表面完整性得到了显著提高,电脉冲辅助硬车淬硬轴承钢的摩擦因数降低了20%,磨痕宽度和深度分别减小了48.7%和93.33%,显著提高了淬硬轴承钢的摩擦磨损性能。

Abstract:

The poor hard turning performance of hardened bearing steels significantly reduced the surface integrity of the workpieces, resulting in poor friction and wear performance of hardened bearing steels. Based on the superiority of electric pulse assisted cutting technology, the surface integrity and surface wear resistance of hardened bearing steels were studied. The results show that the surface integrity of the workpieces is improved significantly, the friction coefficient is reduced by 20%, the width and depth of the wear scar are reduced by 48.7% and 93.33% respectively, and the friction and wear performance of the hardened bearing steels is significantly improved.

Key words: hardened bearing steel, electric pulse assisted hard turning, hard turning performance, surface integrity, wear resistance
