The secret of gold plating on the surface of metal sealing rings: gold plating to improve performance and extend life

preface:

In the industrial field, metal sealing rings are a key sealing element used to prevent liquid or gas from leaking in equipment. In order to further improve the performance and extend the life of metal sealing rings, surface gold plating has become an effective improvement method. This article will delve into the role of gold plating on the surface of metal sealing rings and reveal the various advantages that this gold layer brings to sealing rings.

1. Improve corrosion resistance:

After the surface of the metal sealing ring is gold-plated, a protective layer of metal oxide is formed, which significantly improves its corrosion resistance. This enables the sealing ring to better cope with the erosion of chemical media, slows down the oxidation rate of the metal surface, and thereby extends the service life of the sealing ring.

2. Enhance wear resistance:

The gold-plated metal sealing ring can reduce the wear of the metal surface during the friction process, forming a strong gold coating, which improves the wear resistance of the sealing ring. This is of great significance for equipment with high-frequency vibration or frequent movement, especially in harsh environments such as high temperature and high pressure.

3. Improve sealing performance:

The metal coating on the surface of the metal sealing ring can fill in tiny defects and irregular surfaces, improving the sealing performance. This allows the sealing ring to fit more closely on the sealing surface, effectively preventing medium leakage and improving the sealing effect.

4. Reduce friction coefficient:

The gold-plated metal seal ring reduces the friction coefficient between metal surfaces and improves the movement performance of the seal. This is particularly important for equipment that requires a high degree of flexibility and precise movement, such as hydraulic systems and valves.

5. Improve thermal conductivity:

The metal coating on the surface of the metal seal ring has high thermal conductivity and can conduct heat more effectively, helping to maintain a stable temperature in the system where the seal ring is located. This has a positive impact on applications under high temperature conditions.

6. Beauty and anti-corrosion:

The gold layer on the surface of the metal sealing ring not only enhances its appearance, but also has an anti-corrosion effect. This allows the sealing ring to maintain its good appearance and performance during long-term use in the external environment.

in conclusion:

The role of gold plating on the surface of metal sealing rings is not only to improve corrosion resistance, wear resistance and sealing performance, but also to bring all-round performance improvement to the sealing rings by reducing friction coefficient, improving thermal conductivity and other effects. This makes metal seals more reliable and durable in various industrial applications, and is an important measure to improve equipment efficiency and reliability.
