摘要
通过对十字槽盘头螺钉宏观检查、化学成分分析、硬度测试等物理金相性能分析,确定了其早期失效的主要原因是由于设计技术要求不能满足使用要求,导致螺钉发生批量性滑扣现象,通过对十字槽盘头螺钉表面渗碳淬火处理,并严格控制热处理工艺,确保热处理质量,效果良好。
The paper showed that the design technical requirements can't meet operating requirement,which is the mainreason of the cross-recess screw early failure.It causes the thread slipping.The improvement measures of the carburizationquench on the Surface of the cross-recess screw and the effect is good.
