摘　　要：钻探接头的耐磨性多年来一直是钻探工具中一个重要的研究课题,且已取得较大进展。但所采取的表面强化及硬化措施,比如高频表面淬火、镀铬、离子氮化等,都不同程度地存在着工艺复杂、成本高、效果差等缺点。以钻杆接头常用材料40Cr为试验材料,对其经粉末固体渗硼后的耐磨性、耐蚀性进行了研究,结果表明,渗硼后其耐磨性提高7倍以上,耐蚀性也有明显提高。Wearing resistance of drill rod joint is an important study in drill machine manufacture for years. Surface hardening by high-frequency surface quench, chromium-plating and ion nitrating is not ideal for its complicated technology, high cost and poor result. Boriding test was made on 40Cr steel, the wearing resistance increased to more than 7 times as before, and corrosion resistance also obviously increased.
