Method For Color Marking Metallic Surfaces

摘要

A method of color marking a metal or metal-plated part is described involving setting at least one laser parameter of a laser, such as the power, scan speed, Q-switch, spot size, line separation, and scan repetition, and then energizing a metal containing surface layer of the part using the laser to change the color reflected by the surface layer.

1. A method of color marking a surface of a part, said method comprising:
setting at least one laser parameter of a laser, said at least one laser parameter selected from a group consisting of power, scan speed, Q-switch, spot size, line separation, and scan repetition; and energizing a metal containing surface layer of a part using the laser, wherein following said energizing said metal containing surface layer, said surface layer reflects a light wavelength that is different from a light wavelength reflected by the surface layer prior to said energizing said metal containing surface layer, such that a user views a color of the surface layer following said energizing said metal containing surface layer that is different than a color of the surface layer prior to said energizing said metal containing surface layer.
