Abstract:

The investigation consisted of two parts. In part one, a High Rate Physical Vapor Deposition Process was developed for the deposition of metals, alloys, compounds and dispersion strengthened alloys. The relationship between the deposition temperature, the microstructure and the mechanical properties was studied. The materials resulting from this process were shown to have properties very similar to true engineering materials. These deposition techniques have been developed to the stage where they can be applied to the production of self-supporting shapes or coatings for engineering applications. The second part of this investigation was concerned with the study of the oxidation mechanism of Ni3Al containing yttrium.
