Benefits of technology
The process provides a durable, corrosion-resistant, and reflective chrome finish that withstands thermal cycling and flexing without delamination, meeting the aesthetic and performance standards of the automotive industry while being environmentally friendly.
Problems solved by technology
Chrome plating requires the use of hazardous solutions and bi-products that present numerous environmental issues and problems.
In addition, since chromium is a very hard material, it is well known that a layer of material having high chromium content that is plated on a substrate tends to fracture or “craze” when the substrate is flexed and / or thermally expanded.
However, as stated above, layers of material having high chromium content tend to fracture or “craze” when the underlying substrate is flexed and / or thermally expanded.

Embodiment Construction
[0015] The process of the present invention is for applying a chrome finish to a substrate. The color, tint, shade, etc. of the finish is of great importance since industries, such as the automotive industry, have very specific requirements. In addition, the process must be able to be accomplished without creating environmental problems.
[0016] Examples of substrates to be applied with a finish, or coating, include automotive parts, exterior trim parts, interior trim parts, wheels, rims, hubcaps, bumpers, grills and various furnishings. The substrates can be made, for instance, of glass, plastics, such as automotive plastics, and metals, such as steel and aluminum. In addition, the substrates can be relatively small or relatively large and have simple or complex geometries.
[0017] One chroming process according to the present invention is illustrated by FIGS. 1 and 2. An optional first step is to ensure that the surface of a substrate 10 is smooth and glass-like. This can be accompl...

Abstract
An environmentally-friendly process for applying a chrome finish on a substrate is provided. The chrome finish comprises a thin film of aluminum and chromium deposited onto the substrate by physical vapor deposition (PVD) techniques. The thin layer can consist of three separately deposited metallic layers including a chromium layer sandwiched between a pair of aluminum layers or can consist of a single, simultaneously co-deposited layer of aluminum and chromium in a ratio of 10% to 70% by weight chromium and 30% to 90% aluminum. The structure of a coated substrate is also disclosed.
Description
BACKGROUND OF THE INVENTION [0001] The present invention relates to a method for providing a chrome finish on a substrate, and more particularly, the present invention relates to a chroming process that is environmentally-friendly and that produces a rich, bright, reflective chrome coating traditionally desired by the automotive, firnishing, and other industries. The present invention also relates to a coated substrate having a chrome finish. [0002] Conventionally, nickel / chromium and / or chromium is electroplated on aluminum and steel parts and provides an industry standard for a rich, reflective, chrome finish widely accepted, desired, and used in the automotive, furnishing and like industries. Chrome plating requires the use of hazardous solutions and bi-products that present numerous environmental issues and problems. In addition, since chromium is a very hard material, it is well known that a layer of material having high chromium content that is plated on a substrate tends to f...
