Abstract
A kind of wear resistant coatings consisting of Al

and epoxy resin has been developed
which can be applied to renew the worn surface of anodic oxidation film pf duralumin alloy in military equipments.The effects of the surface treatment of Al

powder by the heterogeneous isotropic distillation process on the wear resistance of the coating were analyzed.The IR spectra of the powder showed that the distillation effectively dehydrates hydrous Al

and succeeds in substituting the hydrate water with butane molecular.The SEM photos demonstrated that the Al
