意大利语Whether the surface of stainless steel balls needs sandblasting treatment mainly depends on their usage scenarios and functional requirements. The following is a detailed introduction to the purpose and applicability of sandblasting treatment:
1. Improve surface roughness:
Sandblasting can create uniform small pits on the surface of stainless steel balls, increase roughness, and thus improve their adhesion or friction in certain assembly structures, making them suitable for situations that require anti slip or increased surface adhesion.
2. Improve the appearance and texture:
Sandblasting can eliminate the processing marks, scratches, and oxide layer on the original surface of stainless steel balls, making their surface present a uniform matte or matte effect, which is more decorative and widely used in art decoration, jewelry, and display spheres.
3. Remove surface impurities and oxide layer:
During the industrial manufacturing process, stainless steel balls may have residual oxide scales, oil stains, or impurities. Sandblasting treatment can effectively remove these pollutants and improve the effectiveness of subsequent treatment processes such as coating, electroplating, or welding.
4. Increase consistency in corrosion resistance:
Although stainless steel itself has good corrosion resistance, uneven surfaces may lead to localized corrosion. Sandblasting treatment can make the surface more consistent and help improve the overall corrosion resistance.
5. Prepare for subsequent processing:
Some stainless steel balls require sandblasting to increase surface adhesion, improve bonding strength and durability after PVD coating, electroplating, spraying and other post-treatment processes.
6. Not applicable for all purposes:
For applications that require high smoothness, high precision, and low friction (such as high-precision bearings or medical equipment), sandblasting may reduce their surface smoothness, making it unsuitable for such high-precision requirements.
