CORROSION-RESISTANT PLATING SYSTEM |
摘要 |
Methods of providing a corrosion-resistant plating on a steel bumper are provided. A galvanized zinc layer is deposited over a steel substrate. A plurality of nickel layers is deposited over the zinc layer. The plurality of zinc layers has at least a first porosity and a second porosity. A chrome layer is applied over the plurality of nickel layers. The porous nickel layer is immediately adjacent the chrome layer such that a stress applied to the chrome layer is distributed over the porous nickel layer. The porous nickel layer delocalizes a stress applied at an impact area to a dispersed area and the dispersed area is larger than the impact area.
