Kind Code:

A1

Abstract:

A metal-resin composite and preparation method thereof with the metal as titanium or a titanium alloy, the composite comprising a metal substrate and a resin layer (2) adhered to a part of a surface of the metal substrate; the part of the surface of the metal substrate having the resin layer attached thereto is distributed with recesses; a part of the resin of the resin layer extends downwardly and fills the recesses; and the oxygen content of a surface layer of the metal substrate is above 1 wt%. The preparation method comprises: soaking the metal substrate in an etching liquid comprising at least one alkali hydroxides to form the recesses on the surface of the metal substrate; and injecting the resin to the surface of the resulting surface-treated metal substrate to form the resin layer.
