AI Technical Summary
Existing light-shielding components suffer from poor temperature resistance, low mechanical strength, easy deformation, and insufficient dimensional stability, as well as problems such as loose black film layer, low hardness, weak adhesion, and easy peeling off to expose the substrate.
Using stainless steel sheet as the substrate, a high-adhesion transition nickel layer system is formed through ultrasonic degreasing, hydrochloric acid activation, electrolytic pre-plating of nickel, and electroless nickel plating. Then, a black film layer is generated by chemical reaction between the blackening working solution and the electroless nickel plating layer, and heat treatment is performed to improve the hardness and adhesion of the film layer.
It significantly improves the temperature resistance and structural strength of the light-shielding component, reduces the risk of deformation, improves dimensional stability, ensures that the film layer is dense and firmly attached, reduces the risk of film layer peeling off and exposing the substrate, and improves the long-term reliability of the light-shielding performance.
