磷化膜质量检测方法上存在的缺陷，给优化钢丝磷化处理工艺、改进磷化膜质量带来较大的困难。根据试验结果，介绍用显微硬度、显微形貌和声发射技术检测钢丝磷化膜质量３种方法的基本原理和特点。
The defects of the quality testing methods of phosphating film have brought great difficulties to the optimization of the phosphating process of steel wire and the improvement of the quality of the phosphating film. According to the test results, the basic principles and characteristics of three methods for testing the quality of the steel wire phosphating film with microhardness, micro-morphology and acoustic emission are introduced.
