Abstract
The yttria dispersion effect on the oxidation resistance of titanium prepared by powder metallurgy has been evaluated between 700 and 900 °C. Yttria additions slightly increase the oxidation rate up to 800 °C and decrease it considerably at 900 °C. The multilayered rutile scale formed on pure titanium prepared by conventional techniques is replaced by a denser rutile scale in the case of titanium prepared by powder metallurgy. Yttria additions raise the temperature at which a more protective dense rutile scale is formed.
