摘要:
A plasma vapor deposited (PVD) coating method. The method includes overlaying a primer polymer layer onto a substrate surface. The method further includes overlaying a chrome metallic layer onto the primer polymer. The method also includes depositing a plasma vapor deposited (PVD) oxide layer of a thickness of 1 to 5 nanometers onto the chrome metallic layer and having a parameter of color change of the underlying chrome metallic layer. The color change may be determined according to the following equation: ΔE*ab=√{square root over ((ΔL*)2+(Δa*)2+(Δb*)2)} L is the color brightness of the oxide layer, and a and b are the color-component dimensions of the oxide and metallic layers. ΔE*ab may be less than 2.3. The method further includes overlaying an exposed polymeric layer onto the PVD oxide layer to form a protective layer at the interface between the exposed polymeric layer and the oxide layer.

A coated metallic part includes a substrate including a metallic surface; a first coating layer supported on the metallic surface and including a first polymer, the first polymer including silicon; and a second coating layer including a second polymer different from the first polymer, the first coating layer being positioned between the metallic surface and the first coating layer. The first coating layer may have a silicon atomic percentage of 5 to 50 atomic weight percent. The first polymer of the first coating layer may have an oxygen-to-silicon ratio of 1.0 to 4.0. The second polymer of the second polymer layer may include at least one of an acrylic polymer, a polyester, an alkyd, a polyurethane, a polyamide, a polyether, a copolymer thereof, and a mixture thereof.

A hem flange treatment method. The method includes air plasma direct spraying a hem flange at an outer edge of an outer panel thereof with a plasma polymer direct spray to cover the outer edge with a protective direct spray region. The method further includes air plasma overspraying an inner cut edge of an inner panel of the hem flange with a plasma polymer overspray to form a protective overspray region that covers the inner cut edge.

A surface treatment for polymeric part adhesion and a treated part is provided. In one aspect, a method for adhesively securing a part to a polymeric substrate is provided comprising providing an adhesive layer having a bonding surface having a first oxygen composition, a part having a bondable surface, and a polymeric substrate having a mating surface. Spray from an air plasma device is directed onto at least a portion of the bonding surface of the adhesive to provide a second oxygen composition on the bonding surface of the adhesive layer, with the second oxygen composition being greater than the first oxygen composition. The adhesive layer is secured between the bondable surface of the part and the mating surface of the polymeric substrate.
