Heat-resistant plasma coatings for metallurgical equipment

Increasingly stringent requirements on the durability and reliability of machines and mechanisms are making it necessary to develop new heat-resistant alloys that can be used for the surface alloying of metallurgical equipment parts. Either new structural steels or heat-resistant alloys that contain iron can satisfy this need. Experimental results have been used to propose an optimum composition of a heatresistant plasma coating based on iron-chromium aluminide Fe-23Cr-15Al-1Y. Use of this material makes it possible to obtain coatings having characteristics better than those of existing coatings. __________ Translated from Metallurg, No. 5, pp. 44–45, May, 2007.
