  In order to improve the oxidation resistances of Mo and Nb alloys, aluminide coatings were developed by lamination cladding. Mo, Nb, and Al sheets with a purity of 99.99 wt% and dimensions of 15 mm×10 mm×0.5 mm were prepared by cutting, followed by the development of a specimen piece by holding the Al sheet between two sheets of Mo or Nb. The specimen wrapped with a Ta foil to prevent oxidation was heated at temperatures of the order of the melting point of Al in a pure Ar atmosphere. On the basis of the elemental analysis by characteristic X-rays, the laminated layers formed on the Mo substrates were found to be composed of MoAl₅, MoAl₄, and Mo₃Al₈. It was also found that the main phase constituting the laminated layers changed from MoAl₅ to Mo₃Al₈ on increasing the temperature from 973 K to 1473 K. In contrast, NbAl₃ was singly formed on the Nb substrate, irrespective of the heating temperatures. However, since NbAl₃ grains have a spherical shape, the NbAl₃ layer was not formed on the Nb substrate.<br>
