On the similarity criteria for the processes of high-temperature sulfur corrosion of heat-resistant alloys

A similarity parameter for the high-temperature sulfur corrosion of heat-re sistant alloys is suggested. This parameter allows to put in order publishe d experimental data of different authors. Original data on the weight loss by 26, C-70B, KC26, and several materials for protective coatings also corr elate with the similarity parameter. The dependences thus obtained allow to predict the operation life of materials (by their weight loss) and to rank nickel-based alloys by their corrosion resistance, depending on their elem ental composition.
