Abstract

The results of investigation of the influence of variable sulfur content on the thermal stability of single crystals of heat-resistant nickel Ni–Al–Co–Re–Ta–Mo–W–Ru–Cr alloy with coating and without it were presented. The negative influence of the increased sulfur content of 0.00030 wt % on the heat resistance of single crystals of this alloy at temperature Т = 1150°С for 500 h on the samples with coating and without it was established.
