The surface treatment of a brake chamber plays an integral role in improving its overall performance. Its core goal is to enhance corrosion resistance, wear resistance and oxidation resistance, thereby extending the service life of the product and ensuring the stability and reliability of the braking system. Through advanced surface treatment technology, not only the functionality of the brake chamber can be improved, but also the market's growing demand for aesthetics and diversification can be met.

Electroplating technology
Electroplating is a surface treatment process that deposits coating metal on the surface of a metal substrate through electrolysis. In the production process of brake chambers, electroplating methods such as galvanizing and chromium plating are often used. These coatings not only improve the corrosion resistance of the product, but also visually enhance its aesthetics. The dense protective film formed by the zinc plating layer can effectively prevent oxidation and corrosion of the base material, while the chromium plating layer significantly enhances the wear resistance of the brake chamber with its excellent hardness and wear resistance, making it more durable in harsh environments. applications are guaranteed.
Spraying technology
Spraying is a technology in which liquid paint is atomized by a spray gun and then evenly applied to the surface of the substrate. In the manufacture of brake air chambers, water-based anti-rust paint and electrophoretic paint are commonly used spray coating methods. These coatings are not only environmentally friendly, non-toxic, and odorless, but can also form a dense anti-rust layer on the surface of the substrate to effectively prevent corrosion. Because of its excellent adhesion and corrosion resistance, electrophoretic paint can form a uniform coating on complex-shaped surfaces, ensuring the reliability of products in different usage environments.
Dacromet treatment
As an emerging metal surface treatment technology, Dacromet treatment uses a coating of zinc, aluminum and other metal powders and inorganic binders, which is formed after baking and solidification. The coating exhibits extremely high resistance to corrosion and wear, significantly extending the service life of the brake chamber. In addition, Dacromet treatment is pollution-free and environmentally friendly, conforms to the environmental protection standards of modern industry, and adapts to the current market requirements for sustainable development.
Chemical conversion coating treatment
Chemical conversion coating treatment is a method to form a dense chemical conversion coating on the metal surface through chemical reactions to improve corrosion resistance. In the manufacturing process of brake air chambers, phosphating treatment is a common chemical conversion coating treatment method. The phosphating film can be closely combined with the substrate to form an effective protective layer to prevent corrosion and wear and ensure the stability of the product in long-term use.
