Excimer laser surface modification of engineering ceramics for adhesive bonding

Simulating fracture in bonded composite joints using cohesive zone models

“…11.6(b) . It has already been reported that the presence of such structures can be benefi cial to joint strength because of the improvement in mechanical keying of the adhesive into the substrate and the increased surface area available for bonding (Man et al , 1997;Zhang et al , 1997). Moreover, aluminium droplets formed globular micron-sized oxide particles on the substrate surface during the treatment; these are represented by the fi ne white dots in Fig.…”

Enhancement of static strength and long term durability of steel/epoxy joints through a fiber laser surface pre-treatment

“…Earlier works have also shown that laser pre-treatments can exert a beneficial action on the strength of adhesive joints [12,13,14,15,16]. Indeed, pulsed laser irradiation can melt the target material, removing contaminants and producing favorable changes in surface chemistry and morphology [17,18].…”

Ballistic testing of surface‐treated alumina and silicon carbide with improved adhesive bond strength

“…Grit blasting can be used to roughen surfaces and thus promote mechanical interlocking but it may also introduce contamination . Chemical changes to the surface of the ceramic can be brought about by laser ablation and these changes have resulted in improved wettability . In previous research, these techniques were applied to alumina and silicon carbide, specifically for armor applications.…”
