Everyone should knowDongguan Precision Casting, Then do you know the mirror treatment of stainless steel precision castings? If you want to know, just follow the editor to read it

In order to further enhance the hardness and gloss of stainless steel precision castings, it is necessary to perform mirror treatment on them. In order to make this treatment process more in line with the requirements, what unfavorable factors need to be eliminated when processing stainless steel castings?

It is found through experiments that the sulfuric acid oxide film is an important factor affecting the high purity and transparency of the oxide film of stainless steel castings. 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 low, and the transparency of the cylinder will decrease.

So make surePrecision cast steelThe effect of the mirror surface treatment of the castings is to reduce the impurity content in the oxide film. Therefore, the thickness, porosity, purity, and sealing quality of the film must be controlled reasonably, and the treatment should not be negatively affected as much as possible.

The impurities in the oxide film are mainly derived from the stainless steel casting itself, and part of it comes from the oxidation bath. Therefore, appropriately reducing the content of alloying elements in the casting can reduce the content of impurities 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 was successfully completedLost wax castingThe mirror surface treatment process is also a certain degree of difficulty. To achieve good results, it is necessary to eliminate various influencing factors, and to give full play to the effect of the process, so that the quality of the entire stainless steel casting will also be improved.

After the introduction of the editor, does everyone have a clearer picture of the mirror treatment of stainless steel precision castings?
