轴承套圈成品及锻件水浸超声检测技术应用

摘要

Water immersion ultrasonic testing to the bearing rings ifnished products and forgings can ifnd out the inner hairline cracks (e.g. the inside cracks of raw materials, forging cracks, heat treatment cracks) effectively. This method can control the quality of bearings and improve the service life evidently.%通过对轴承套圈成品及锻件进行水浸超声检测，发现其内部原材料裂纹、锻造及热处理产生的细小裂纹，实现对轴承产品的质量控制，提高轴承的使用寿命。
