摘要	There exist serious interfacial reactions in squeeze-casting aluminum borate whisker reinforced 6061Al composites. To control the spinel reactions a sol-gel coating method was used to deposit gamma-Al2O3 and alpha-Al2O3 ceramic coatings on aluminum borate whiskers. TEM observations of coating morphology indicate that nanostructured alumina coatings are uniformly deposited on whisker surfaces, with a thickness of about 30-50 nm. Ball-milling has an important effect on final mechanical properties of the composites. gamma-Al2O3 and alpha-Al2O3 coatings were found to be effective in controlling the interfacial reactions, by completely preventing the diffusion of magnesium from matrix/coating interface to coating/whisker interface.
