摘要
对下游曲轴锻造厂提供的异议曲轴上的磁痕进行了着色渗透、磁粉探伤、金相和扫描电镜等系统检测,结合磁粉探伤的原理,阐明该磁痕属于发纹类磁痕,其本质是原材料中的一种硫化物偏聚现象,不会影响曲轴的使用性能。
Abstract
The magnetic particle indication appeared on objected crank shaft which provided by the downstream forging plant was systematically tested and analyzed by dye penetrant inspection, magnetic particle inspection, metallography inspection and scanning electron microscope analysis. Combined with the principle of magnetic particle inspection, it was concluded that the magnetic particle indication belonged to capillary crack, whose essence was one segregation phenomenon of sulfide, and it could not affect the service performance of crank shaft.
