Chrome plating plays an important role in automobile manufacturing. It can significantly enhance the color of the car, making the appearance of the vehicle more bright and eye-catching. This surface treatment can not only improve the aesthetics of the car, but also improve the strength and hardness of the vehicle, thereby increasing its wear resistance. This also means that the surface of the car can be maintained in good condition after long-term use and various climatic conditions.

However, this process of increasing strength and hardness also reduces the plasticity and toughness of the material. Nevertheless, the advantages of chrome plating far outweigh its disadvantages. For example, chromium can effectively improve the oxidation and corrosion resistance of steel, which is essential for exposed automotive parts.

In addition, chrome plating can also protect some plastic parts on the car, and protect the paint surface without the handle. These advantages make chrome plating a very popular surface treatment method in automobile manufacturing.

The bonding force between the chromium plating layer and the base metal is very strong, and even in some cases, its bonding strength can exceed the bonding strength of the steel itself. This allows the chromium plating to work at high temperatures, even when the temperature reaches more than 500 degrees Celsius, its mechanical properties will change. In addition, the thermal conductivity of chromium is also very good, second only to copper, 40% higher than pig iron.

However, chrome plating also has some disadvantages. For example, its deposition efficiency is low, which leads to a decrease in productivity. At the same time, in the case of poor lubrication conditions, the wear resistance of the chromium coating will also be reduced. Nevertheless, the wear resistance can be effectively improved by adopting technical means such as porous chromium plating.
