What is sandblasting and electrolytic? What’s the advantage?

Sandblasting is a method of cleaning metal surfaces by spraying sand or other abrasives at high speeds, which removes dirt, oxidized layers, and minor scratches from metal surfaces, making them smoother, more uniform, and enhancing their adhesion to coatings. This type of treatment is applicable to a wide range of metal materials, including stainless steel, aluminum alloys, titanium alloys, etc. It is widely used in the fields of architectural decoration, kitchenware, medical equipment, aerospace, automobile manufacturing and electronic products.

Electrolytic treatment is a process in which a metal film is attached to a metal surface through electrolysis, preventing corrosion, improving weldability, electrical conductivity and enhancing aesthetics. Electrolytic treatment usually includes electroplating of gold, silver, nickel, zinc, tin, etc. These metal films protect the substrate from corrosion and increase the aesthetics and functionality of the substrate.

Using a combination of sandblasting and electrolytic treatment can provide the following benefits:

Improve coating adhesion: sandblasting increases the roughness of the metal surface, which improves the bonding between the coating and the metal surface, making the coating stronger.

Enhance the corrosion resistance of the metal: electrolytic treatment can form a protective film on the metal surface, effectively preventing corrosion and prolonging the service life of the metal.

Improve mechanical properties: sandblasting can improve the mechanical properties of metal, such as fatigue resistance, while increasing the surface hardness and improving the service life of mechanical parts3.

Enhance aesthetics: the metal surface after sandblasting and electrolysis treatment is smoother and more uniform, which not only improves the uniformity and aesthetics of the coating, but also enhances the overall aesthetics.

In summary, the combined use of metal sandblasting and electrolytic treatment can not only improve the quality of metal surface treatment, but also enhance the functionality and aesthetics of the metal, which is an effective method of metal surface treatment.
