摘要：
An influence of Cr additives (1.5-27.6%) on high-temperature corrosion processes in alloys is investigated. The alloys of Ni-Cr, Ni-Cr-Al, Ni-Cr-(Al+Ti), Ni-Cr-Co-W-Mo-(Al+Ti) systems are tested in the combustion products of aviation kerosene, containing 1% Si, with addition of Na salt water solution. The class of heat-and-corrosion resistant alloys (ChS70VI, 3MI-3, SNL-1, ChS91VI, 3MI-11) with moderate or high (30%) content of Cr, Ti/Al more than 1, and balanced content of refractory and rare earth elements is created.
