  • The aesthetic enhancement or modification of articles or components made of non-ferrous metals
    Patent number: 5503691
    Abstract: A method of enhancing the appearance of a polished surface of an artifact is provided in which the artifact is formed from a non-ferrous alloy, in particular, but not exclusively, a precious metal alloy, chosen to exhibit a martensitic and a parent phase structure. The surface, or relevant part thereof, is polished in one of the phases, usually the parent phase, followed by heat treatment to effect a phase transformation, generally to the martensitic phase. This phase change causes a visible surface effect to the polished surface which may be described as a spangle effect.
