A coloring method and device based on metal material surface coloring technology

Abstract

The invention discloses a coloring method and device based on the surface coloring technology of the metal material. According to the oxidability characteristic of the to-be-processed material, the material to be processed is heated through the low-power laser, the auxiliary oxidizing gas is used as an oxidizing agent, rapid controllable oxidation reaction of a to-be-processed region material andan oxidizing agent can be achieved by utilizing instant high temperature generated by low-power nanosecond pulse laser, the laser enables the surface of the material to be subjected to controllable oxidation, so that a transparent or semitransparent oxide layer thin film can be generated; and according to the photochemical effect and the thin film interference effect, different colors can be displayed on the surface of the processed material due to the fact that different laser parameters are selected. By means of the method and device based on the surface coloring technology of the metal material, coloring processing of the surfaces of materials such as titanium alloys or the surfaces of jewelry can be realized, the effect of protecting the internal metal is achieved, and the wear resistance and the corrosion resistance of metal or jewelry can be improved.
