Abstract

General features of structural changes in silicide coatings on molybdenum during vacuum annealing in the temperature range between 1850 and 1920°C have been studied by electron microscopy, metallography, and x-ray phase analysis. The kinetics of eutectic MoSi2-Mo5Si3 formation and structure are studied. It is found that fusion of the eutectic compound coating makes it possible to reduce defects substantially and thus improve surface layer quality.
