Improving the corrosion resistance of brass plates can be achieved through a variety of methods. Here are some commonly used methods:
Increase zinc content: Increasing zinc content in brass plates can effectively improve corrosion resistance. Zinc is an active metallic element that reacts preferentially with oxygen in the air to form a dense oxide film on the surface of brass to prevent further oxidation.
Surface treatment: Coating the surface of brass plates can effectively improve corrosion resistance. Commonly used surface treatment methods include tin plating, chrome plating, spraying, etc. These methods can form a protective film on the brass surface to prevent air and moisture from corroding the substrate.
Heat treatment: The corrosion resistance of brass plates can be improved through heat treatment. Heating the brass plate to a certain temperature and keeping it warm for a certain period of time can promote the diffusion of copper and zinc and make the elements in the brass plate more evenly distributed. It can also eliminate internal stress and improve corrosion resistance.
Passivation treatment: Passivation treatment is a commonly used method to improve corrosion resistance. The brass surface is passivated through pickling, alkali cleaning and other methods to form a protective film, which can effectively improve corrosion resistance.
Improve the use environment: In harsh environments such as humidity, high temperature, and salt content, the corrosion resistance of brass plates will decrease. Therefore, you should try to avoid using brass plates in harsh environments during use.
To sum up, improving the corrosion resistance of brass plates can be achieved by increasing zinc content, surface treatment, heat treatment, passivation treatment and improving the use environment. Choosing the appropriate method according to the actual situation can improve the corrosion resistance of the brass plate and extend its service life.
