Everyone should know the stainless steel precision castings, then do you know the mirror treatment of stainless steel precision castings, if you want to know, follow along with the editor
In order to further strengthen the hardness and gloss of stainless steel precision castings, it is necessary to perform a mirror surface treatment, and in order to make this treatment process more in line with the requirements, what disadvantages need to be excluded when processing stainless steel castings?
It was found through experiments that the sulfuric acid oxide film is an important factor affecting the high purity and transparency of the stainless steel casting oxide film. Its thickness, porosity, purity, and sealing quality will directly interfere with the mirror effect of the casting, such as when the oxide film contains If there are more impurities, its purity will be lower and the transparency of the cylinder will decrease.
Therefore, to ensure the mirror surface treatment effect of stainless steel castings, it is necessary to reduce the impurity content in the oxide film, so the thickness, porosity, purity, and sealing quality of the film must be controlled reasonably, so as not to adversely affect the processing.
The impurities in the oxide film mainly come from the stainless steel casting itself, and some are from the oxidation bath. Therefore, by appropriately reducing the content of alloy elements in the casting, the impurity content can be reduced as much as possible. At the same time, reducing the impurity ions in the bath and keeping the bath fresh can also improve the purity of the oxide film.
It can be seen that it is also difficult to successfully complete the mirror surface treatment process of stainless steel castings. In order to achieve good results, it is necessary to exclude various influencing factors and make the effect of the process good, so that the quality of the entire stainless steel castings is also Will rise with it.
After the introduction of the editor, is everyone's mirror treatment of stainless steel precision castings clearer?
