Abstract:
Disclosed herein is an aging resistance coating film for a hub, sequentially comprising an aluminum alloy matrix, a silane conversion film, a high-gloss organic resin coating, a periodic variable alloy black chromium coating film and a transparent resin coating. In the coating film, the thickness of the black chromium coating film is increased and the blackness thereof is adjusted according to different content of C. The residual stress of the deposited metal layer is reduced, the problem of cracking during heating and rapid cooling of the coating film is solved, and the binding force between the coating film and the underlying high-gloss resin material is improved. Also disclosed herein is a method for forming an aging resistance coating film for a hub, comprising: (1) silane pretreatment, (2) spraying of high-gloss medium powder, (3) PVD coating, and (4) spraying of transparent powder.

Claim (Index 1):
An aging resistance coating film for a hub, sequentially comprising: an aluminum alloy matrix, a silane conversion film, a high-gloss organic resin coating, a periodic variable alloy black chromium coating film and a transparent resin coating;\n the periodic variable alloy black chromium coating film is a C\u2014Cr periodic variable alloy black chromium coating film, 90%-0 of C component changes periodically, 10-100% of Cr metal component changes periodically, Cr is primed first with a thickness of 5-10 nm, then the double targets are opened, C and Cr change periodically in accordance with the ratio of 10:90 to 90:10 for coating with a thickness of 80-150 nm, finally only the pure Cr target is opened to form a thickness of 5-10 nm, and the thickness of the entire film is 100-170 nm; the thickness of the high-gloss organic resin coating is 120-250 \u03bcm, and the thickness of the transparent resin coating is 80-150 \u03bcm.
