Abstract

The factors responsible for modifications to the wettability characteristics of metallic materials after high power diode laser (HPDL) treatment were analyzed. Interaction of EN3 and EN8 mild steel with HPDL radiation resulted in the wettability of mild steels. These changes were due to the modifications to the surface roughness, the increase in the polar component of the surface energy and changes in the surface O₂ content. It was found that the surface roughness was the primary factor influencing the contact angle θ and therefore the wettability of the mild steels.
