In modern industrial production, stainless steel is widely used in various fields due to its excellent corrosion resistance, wear resistance, and aesthetics. However, after a period of use, stainless steel will appear problems such as oxidation and corrosion, seriously affecting its service life and performance. To solve this problem, scientists have developed a process called "passivation treatment", which can effectively improve the corrosion resistance and service life of stainless steel. So, what changes will occur after stainless steel passivation? These knowledge points you absolutely can't miss!
Firstly, let's understand what passivation treatment is. Passivation treatment is a process that forms a stable and tight protective film on the metal surface through chemical reaction. This protective film can effectively prevent the metal from contacting with oxygen, moisture and other corrosive substances in the environment, thus prolonging the service life of the metal. For stainless steel, passivation treatment not only improves its corrosion resistance, but also improves the smoothness and aesthetics of its surface.
So, what changes will occur after stainless steel passivation? There are mainly the following aspects:
1. Improved corrosion resistance: Passivation treatment can form a stable chromium oxide protective film on the surface of stainless steel, which can effectively prevent stainless steel from contacting with oxygen, moisture and other corrosive substances in the environment, thereby improving the corrosion resistance of stainless steel.
2. Improved wear resistance: Passivation treatment can also improve the wear resistance of stainless steel. This is because passivation treatment can form a protective film with high hardness on the surface of stainless steel, which can improve the anti-wear ability of stainless steel.
3. Improved antioxidant property: Passivation treatment can also improve the antioxidant property of stainless steel. This is because passivation treatment can form a stable chromium oxide protective film on the surface of stainless steel, which can effectively prevent stainless steel from reacting with oxygen at high temperatures to generate iron oxide.
4. Improved surface smoothness and aesthetics: Passivation treatment can also improve the surface smoothness and aesthetics of stainless steel. This is because passivation treatment can form a colorless and transparent protective film on the surface of stainless steel, which can make the surface of stainless steel more smooth and bright.
In general, after passivation treatment of stainless steel, its corrosion resistance, wear resistance, antioxidant property and surface smoothness will be significantly improved, thus effectively prolonging its service life and improving its performance. Therefore, passivation treatment is an important process in modern industrial production that cannot be ignored.
