Abstract
It is quite possible to bring about changes in the wettability characteristics of a two-stage ceramic tile grout by means of high power diode laser (HPDL) surface treatment. Such changes manifest themselves as a reduction in the contact angle, , and are due to the HPDL inducing changes which reduce the surface roughness, increase the surface O 2 content and increasing the polar component of the surface energy. What is more, HPDL treatment of the two-stage ceramic tile grout surface was found to effect an improvement in the bonding characteristics by increasing the work of adhesion, W ad . Along with wettability experiments carried out with selected liquid-metals, an electronic approach was used to identify the bonding characteristics of the two-stage ceramic tile grout before and after HPDL. It is thought that HPDL induced changes to the two-stage ceramic tile grout produced a surface with a reduced bandgap energy which consequently increased W ad by increasing the electron transfer at the metal-oxide i...
