WETTABILITY OF METALLIC OXIDES. APPLICATION TO ADHESION

摘要

The various components of the surface energy of SiO_2 taken as a model oxide were experimentally determined using low temperature wettability experiments in a two-liquid configuration. Moreover a special attention is paid to the comparison between the surface charges deduced from electrocapillarity measurements and those obtained by direct A.F.M. measurements. Then an analysis of results in terms of acid-base interactions is proposed and extended to AISI 304 stainless steel surfaces with various surface treatments. The ability of these surface treatments to optimize the adhesion energy of AISI 304 / Epoxy joining is finally discussed.
