An article has deposited on at least a portion of its surface a decorative and protective multi-layer coating comprising at least one nickel layer, a tin-nickel alloy layer, a chrome layer, a layer of titanium or titanium alloy, and sandwich layer comprised of layers comprised of titanium or titanium alloy alternating with layers comprised of titanium compound such as titanium nitride or titanium alloy compound such as titanium nitride, and a layer of titanium compound or titanium alloy compound. The coating provides abrasion and corrosion protection to the underlying substrate and also protects the substrate from attack by chemicals such as acids and bases while being crack resistant and resistant to galvanic corrosion. |
