Abstract
A decorative surface treatment of hardenable metals to achieve a three dimensional textured surface with the appearance of mokume gane or Damascus steel. The annealed surface of the metal is selectively hardened by a laser in zones next to unhardened areas. The unhardened areas are selectively eaten away by abrasives in a way that allows deep texture relief.
Claims5
A decorative surface treatment for metals comprising:
- (a) a single hardenable metal such as titanium, stainless steel, or carbon steel in an annealed state,
- (b) selectively heating the surface of said metal with a laser to create zones of hardened and unhardened material,
- (c) and means for selectively abrading unhardened portions of the metal surface away to create a three dimensional textured surface with the appearance of Damascus steel or mokume gane.
