Analysis on Reasons of Pocked Surface of Cementite Gears

通过对齿轮在热处理过程中产生“麻点”缺陷原因的探析,指出热处理过程中盐的质量和操作不当及渗碳过程是产生“麻点”的主要原因,其本质都属于不完全氧化所产生的腐蚀,并提出了简明的预防方法。

According to the discussion about comentite gears picked surface, the author points out the main masons of pock gears surface in the heat treatment process arc the quality of salt and the improper operation. The essence is incomplete oxygenation rot. Furthermore, the author puts forward the compendious preventive measures.
