Abstract : Previous studies showed that coatings obtained by the condensation in vacuum of Cr vapors on the surface of Mo samples had good protective properties, but that their service life decreased considerably when they were subjected to temperature fluctuations. A study was made on the effect of temperature on internal stresses in chromium coatings on molybdenum produced in various vacuum conditions and having various strengths of adhesion of the coating to the substrate. The adhesion strength of coatings applied to the surfaces of oxidized and nonoxidized Mo were about the same and were similar to the strength of the coating. (Author)
