(Summary description)Through experiments, it can be seen that hydrochloric acid oxide film is a key factor that endangers the purity and clarity of the oxide film on stainless steel precision castings. Its thickness, porosity, purity, and grouting reinforcement quality all immediately affect the mirror effect of the casting. If there are many impurities in the oxide film, its purity will decrease, and the clarity of the cylinder section will be reduced. Therefore, to ensure the actual effect of mirror treatment on stainless steel plate precision castings, it is necessary to reduce the impurity content in the oxide film. Therefore, it is necessary to effectively control the thickness, porosity, purity, and sealing quality of plastic films, so as not to affect production and processing as much as possible. The impurities in the oxide film mainly come from the stainless steel plate precision casting itself, and a part comes from the oxidation bath. Therefore, moderately reducing the content of alloy elements in precision casting parts can greatly reduce the impurity content. At the same time, reducing the impurities and cations in the tank liquid, maintaining the freshness of the tank liquid, can also improve the purity of the oxide film. From this, it can be seen that the mirror treatment processing process of stainless steel plate precision castings cannot be successfully completed. To achieve good results, it is necessary to remove various influencing factors, so that the processing technology can fully exert its excellent effects, and the quality of all stainless steel precision castings will also be correspondingly improved.
