Abstract

Marked changes in the wettability characteristics of EN8 mild steel were observed after high power
diode laser (HPDL) surface treatment of the metal. The morphological, microstructural and wetting
characteristics of the steel were determined using optical microscopy, scanning electron microscopy
(SEM), X-ray photoemission spectroscopy (XPS) and wetting experiments by the sessile drop
technique. Improvements in the wetting action of the mild steel after HPDL surface treatment were
identified as being the result of: The HPDL induced melting of the mild steel surface which brought
about a reduction of the surface roughness; The small increase in the polar component of the surface
energy and the increase in the surface O2 content of the mild steel resulting from HPDL treatment.
This work has demonstrated that the use of HPDL radiation to alter the wetting characteristics of mild
steel in order to facilitate improved enamelling is a real possibility.
