METHOD FOR MAKING PATTERNS ON METAL ARTICLE AND THE RESULTING METAL ARTICLE |
摘要 |
A method for making patterns on a metal article comprises providing a metal substrate having an outer surface. A light-absorbing coating is formed on selected regions of the outer surface to reduce the surface laser reflectivity of the metal substrate. The selected regions cooperatively have a shape of a desired pattern. The selected regions are treated by laser-quenching, thereby hardening the selected regions. The outer surface is sandblasted, enabling the outer surface besides the selected regions to have a greater surface roughness than the selected regions. A metal article made by the method is also provided.
