The effect of electrolytic etching on the adhesive strength of epoxy-phenolic resin to aluminum was investigated by measurements of peel strength and SEM-observation of aluminum surface. Electrolytic etching increased the peel strength of resin to aluminum. It was presumed that the main factors which influenced peel strength were the surface roughness, the area of flat part with sub-microscopic pores whose size was about 1000Å_??_, the number of pores, the presence of facet-like plane located in concave part and smut.In order to clarify the influencing factors, we examined how the surface of aluminum was changed by chemical treatment after electrolytic etching. Chemical etching was achieved to remove smut or to resolve surface of aluminum. It was clarified that the smut on the surface of aluminum decreased peel strength extremely and facet-like plane did not influence peel strength so much. Peel strength was increased by the presence of many sub-microscopic pores and flat parts around concave surface. Peel strength of epoxy-phenolic resin to electrolytically etched aluminum was superior to that of conventional surface treatments such as Cr3+ or Cr6+ chromate and boehmite.
