抄録

The effect of Mg on the deoxidization of the Al₂O₃ surface film has been examined by means of the investigation on the chemical bonding changes at the topmost-surface of the aluminum alloy powder particle at the elevated temperature by using SR-XPS analysis. It was clarified that the diffusion of Mg solved in the matrix to the A12O3 surface film started in the aluminum alloy powder with Mg at 573 K, and the deoxidization reaction of the Al₂O₃ surface film by Mg occurred over 670 K and it completed around 774 K. SEM observation showed that the holes caused by the deoxidization of the Al₂O₃ film existed at the particle surface. On the other hand, the aluminum alloy powder without Mg did not show such a deoxidization during heating to 825 K and its surface was covered with the Al₂O₃ film.
