Abstract
Mechanofusion is a novel powder processing technique, in which raw powdered materials are fed into the apparatus, and through mechanical-thermal interactions, the powder characteristics are changed, e.g., shape, size, and composition distribution. Mechanofusion has been used in this study to produce intermetallic nickel aluminide compounds and composite powders as feedstock for vacuum plasma spraying. Significant effects of the mechanofusion production route on the powder characteristics and spray deposition features have been observed.
