Beschreibung
Zusammenfassung:	The invention relates to a non-hydrogen embrittlement and low surface damage zinc powder sherardizing processing process of a machined steel product, belongs to the zinc powder sherardizing technology in the field of thermal surface processing and aims at solving the problems of hydrogen embrittlement and surface damage of the machined steel product in the zinc powder sherardizing process. According to the technical scheme, according to a zinc powder sherardizing method of the machined steel product with no hydrogen embrittlement and low surface damage disclosed by the invention, with the adoption of the technical scheme of antirust processing after steel product machining, non hydrogen embrittlement zinc powder sherardizing pre-processing, non surface damage zinc powder sherardizing pre-processing and low surface damage heating zinc sherardizing processing, the machined steel product is capable of realizing non-hydrogen embrittlement and low surface damage zinc powder sherardizing.
