Abstract��The end face of the gear are scrapped due to a large number of holes on the surface. Macrostructure, microstructure, chemical composition are analyzed by means of scanning electron microscopy, energy dispersive spectrometry, optical microscopy and hydrogen analysis, and scrap reasons were discussed. The results showed that raw material had serious banded segregation, and end face segregation in corrosive environment formed holes, which made the gear scrapped.
