目前磁粉探伤技术在工业上已得到广泛应用,已成为确保产品质量的一种重要的无损检测手段。由于冶金技术水平所限或冷、热加工工艺控制不当,均有可能造成原材料或产品构件的表面(或近表面)产生各类缺陷,对这些缺陷可用磁粉探伤法检出。而目前国
At present, magnetic particle inspection technology has been widely used in industry and has become an important nondestructive testing method to ensure product quality. Due to the limited level of metallurgical technology or the improper control of cold and hot processing technology, all kinds of defects may be generated on the surface (or near surface) of the raw material or product component, and the defects can be detected by magnetic particle inspection. The current country
