AbstractHigh temperature oxidation resistant coatings were prepared by mixing Al powder, Sn powder, SiO2 powder, styrene acrylic emulsion, polyvinyl alcohol and sodium carboxymethyl cellulose according to the determined ratio. The effects of heat treatment temperature and holding time on anti-oxidation properties were discussed. The microstructure of the coated surface and uncoated surface, elements diffusion and interface phase structure were analyzed by light microscope, field emission scanning electron microscopy, energy spectrum analysis instrument and X-ray diffraction instrument. The results show that the aluminum based high temperature oxidation coating effectively prevents surface oxidation scale forming on the surface of titanium ingot during thermal processing. Al2O3-TiAl and TiAl3-Ti phase with good protective properties are formed in the transition layer, and it is worthy to note that good oxidation resistant effect is achieved when heat treatment temperature is 1050 degrees and holding time is 8 h.
