AbstractHigh temperature oxidation resistant coatings were prepared using Al powder as main raw material and Sn powder, SiO2 powder, styrene acrylic emulsion, polyvinyl alcohol, sodium carboxymethyl cellulose as burdening. Subsequently, the coatings were sprayed onto the surface of titanium substrate, and then the sample was placed at constant temperature of 1050 degrees C for 8 h; the surface topography was also compared for the flakes with coating or not. The microstructures of the exposed surface and sprayed surface were analyzed by optical microscope, the interface of coating microstructure and elements diffusion were analyzed by field emission scanning electron microscopy and energy spectrum analysis instrument, and the interface phase structure was analyzed by X-ray diffraction. The results show that high temperature oxidation resistant coatings at titanium billet surface have no cracks, without dropping from the surface and remaining metallic luster. It can effectively slow down the high temperature oxidation process of titanium billet during the thermal procedure. The effect of the coating thickness on the thickness of Ti-Al diffusion layer is not significant; the Al2O3-TiAl layers and TiA13-Ti multilayers co-form the diffusion layer; moreover, the excellent coating thickness is about 50 mu m.
