ABSTRACT:
A process for enhancing the absorbent surface characteristics of a material having low carbon solubility or whose properties are not adversely affected by alloying with carbon comprises the step of mixing the material with lampblack in order to deposit a coating of lampblack on the material. Furthermore, the lampblack acts as a deoxidizing and fluxing agent to clean the substrate surface and promote effective wetting by the molten material during a laser processing procedure.
