The said anodic oxidation coatings surface where manufacturing method and its composite null of the composite of the aluminum

摘要

This invention offers the manufacturing method and resistance exfoliation characteristic of the composite of the aluminum material and the plastic compact which can be produced in high efficiency and the stable strong composite whose mechanical strength is large. Manufacturing method of the above-mentioned composite of this invention forms the anodic oxidation coatings 2 which, possesses the countless hole 3 where the diameter which opens to the surface aluminum material 1 by anodic oxidation processes in electrolysis bath of phosphoric acid or sodium hydroxide, is above 25nm with injection molding and the like portion 6of a plastic compact 6 is obtained into countless hole 3 of the said anodic oxidation coatings 2 eats binding designates that it connects to a state where as feature, can obtain the composite P which because of this possesses the above-mentioned quality simply.
