Some Regularities in the Precipitation of Molybdenum Oriented Coatings from Gaseous Phase

Abstract

The paper describes an experiment in precipitation of molybdenum from gaseous phase in an attempt to determine the factors which affect the orientation of chemical vapor deposited coatings. In the experiment, high- temperature pyrolysis of molybdenum pentochloride was used. Application of the coating was accomplished at three fixed temperatures of the base: 1120, 1300, and 1430C. Two types of bases were used: rolled molybdenum, foil and tablets. X-ray analysis of the coatings was performed. Change in the temperature of the base and change in pressure of the gaseous phase were found to affect the coating process. Texture of the base was found not to have a dominant effect on texture of the coating.
