Improvement in the Oxidation Resistance of Tungsten by Sol-Gel Derived AI2O3 Coating

摘要：

An Al2O3 coating was prepared from aluminum isopropoxide as precursor on tungsten substrate. The dependences of crystalline and phase in Al2O3 coating on temperature were studied. The results show the coatings being compact, uniform and crack-free can be obtained by suitable experiment. The main phase of coating is α-Al2O3. Compared to the uncoated specimens, the ones with coatings synthesized by sol-gel process provide excellent oxidation resistance at high temperature.
