热处理后工件表面残盐清除,在整个机械加工防锈过程中是一个重要环节。表面残盐的清除程度,直接影响到工件表面的质量。残盐清除干净的工件表面,就可避免工件在加工过程中遭到因残盐这个因素而引起的锈蚀。特别是具有深孔、沟槽、螺纹等形状较复杂的非加工或加工完毕的工作面,尤为突出。这一点早已引起人们的重视。近几年来,国内许多工厂已开始这方面的试验研 After the surface treatment of residual salt removal after heat treatment, in the whole process of rust-proof machining is an important part. Surface residual salt removal, a direct impact on the quality of the workpiece surface. Residual salt to remove the clean surface of the workpiece, the workpiece can be avoided in the process of corrosion due to residual salt caused by this factor. Especially with deep holes, grooves, threads and other complex shapes of non-processing or processing of the face, especially prominent. This has long drawn people’s attention. In recent years, many factories in China have begun to test this aspect
