Preventing Scratches and Oxidation on the Surface of Magnesium Alloy Kitchen Appliances

1. Composite Oxidation/Anodizing Process
Composite oxidation technology forms a dense, hard layer within the oxide film, significantly improving wear resistance and corrosion resistance. Salt spray testing can reach 200 hours, preventing scratches and oxidation.

2. Dual Protection with Chemical Conversion Film + Organic Coating
By superimposing a chromium-free chemical conversion film and an organic coating, a protective layer is formed on the substrate surface, blocking oxygen and moisture and reducing the oxidation rate.

3. Surface Hardening Treatment and Fine Polishing
Using micro-arc oxidation or fluoride anodizing (MgF₂) to form a hard ceramic film, the hardness is increased to HRC≥70, and the scratch depth is controlled below 0.2mm.

4. Company Advantages and Implementation

Ningbo Victor Electrical Technology possesses semi-solid magnesium alloy semi-melt injection molding and aluminum alloy die casting workshops, enabling high-quality surface treatment directly during the production stage. This ensures that every kitchen appliance leaves the factory with reliable performance, including scratch resistance and oxidation resistance.
