How to improve the wear resistance and anti-fingerprint ability of Brass plate through surface treatment?
Publish Time: 2024-10-22
As a commonly used metal material, Brass plate is widely used in many fields. However, its wear resistance and anti-fingerprint ability often need to be improved through specific surface treatment.
An effective method is to use electroplating process. For example, hard chrome plating can significantly improve the hardness and wear resistance of Brass plate. Hard chrome plating has the characteristics of high hardness and low friction coefficient, which can effectively resist wear. At the same time, chrome plating can also play a certain barrier role, preventing brass from direct contact with the external environment and reducing the occurrence of oxidation and corrosion. During the electroplating process, process parameters such as current density, temperature, time, etc. need to be strictly controlled to ensure the quality and uniformity of the coating.
Another method is to perform chemical conversion film treatment. By treating the surface of Brass plate with a specific chemical solution, a dense conversion film can be formed. This conversion film can improve the corrosion resistance and wear resistance of Brass plate, and also has a certain anti-fingerprint ability. Common chemical conversion films include phosphating film, chromate film, etc. Different conversion films have different performance characteristics, which can be selected according to specific application requirements.
In addition, physical vapor deposition (PVD) technology can also be used. PVD technology can deposit a layer of high-hardness, wear-resistant film, such as titanium nitride, titanium carbide, etc., on the surface of the brass plate. These films not only have excellent wear resistance, but also have good anti-fingerprint ability. PVD technology can accurately control the thickness and composition of the film, thereby achieving customized treatment of the surface performance of the brass plate.
When performing surface treatment, the compatibility of the treated brass plate with other materials also needs to be considered. For example, if the brass plate needs to be in contact with materials such as rubber and plastic, a suitable surface treatment method needs to be selected to ensure good bonding and wear resistance between the two.
In short, through surface treatment technologies such as electroplating, chemical conversion film treatment and PVD, the wear resistance and anti-fingerprint ability of the brass plate can be effectively improved. When choosing a surface treatment method, factors such as cost, performance requirements and application environment need to be considered comprehensively to achieve the best treatment effect.
