Combination of precious metals and black titanium

Abstract

This invention proposes a composite component of precious metal and black titanium, comprising a black titanium metal component and a precious metal component. The black titanium metal component is made of either pure titanium or zirconium-titanium alloy, and a black titanium oxide film is generated through a surface blackening treatment. At least one interlocking part is formed on the surface of the black titanium metal component by laser engraving. The precious metal component has at least one wing and is a thin sheet element that can cover the outer surface of the black titanium metal component as a shell. The wing of the precious metal component and the interlocking part of the black titanium metal component are interlocked together to form the composite component of precious metal and black titanium. This invention maintains the surface luster and aesthetics of the precious metal while minimizing the weight of the precious metal and the material consumption of the dissimilar metal bonding.
