Abstract
An alkali-proofed cast aluminum product having a wear-resistant surface layer thereon comprising a number of wear-resistant granules with partially projected form inserted into the surface of a base material containing aluminum as a main component, cavities open to the surface of said base material being filled with a first alkali-resistant impregnating material, and the whole surfaces of the base material including the wear-resistant granules being covered with a coating of a second alkali-resistant material is excellent in alkali resistance and prevents the wear-resistant surface from the falling out of wear-resistant granules.
