| description | The invention belongs to a surface treatment processing technology, and relates to an oxidation processing method for an iron-based alloy part. The processing flow comprises the steps of oil removal, activation, primary oxidation, secondary oxidation and passivation. The process is developed for specific materials; production on production lines of different specifications is realized by adjusting parameters and processes; a phosphating process is replaced, hazardous wastes such as phosphating waste residues are not generated, and the production cost and the environmental protection cost are reduced; through batch examination, the finished product meets the process requirement and the acceptance specification; the first-time delivery inspection qualified rate is increased to 92% from 86%; the raw materials and the environmental protection cost are saved by more than 47 yuan per ten thousand of products; the invention meets the requirements of safety, environmental protection, occupational health, production e |
