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.
