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.
