LAP Lambert Academic Publishing Zharoprochnye nikelevye splavy: Sostav, struktura, svoystva, tekhnologii

V svyazi s problemoy konversii aviatsionnye konstruktorskie byuro i motorostroitel'nye zavody vse shire zanimayutsya razrabotkoy novykh i modernizatsiey sushchestvuyushchikh gazovykh turbin raznogo naznacheniya. Mirovaya praktika ekspluatatsii statsionarnykh gazovykh turbin pokazyvaet, chto zharoprochnye nikelevye splavy aviatsionnogo naznacheniya nadezhno rabotayut v usloviyakh vysokokachestvennykh topliv v diapazone temperatur 1000-1100°S. V usloviyakh ekspluatatsii turbin pri bolee nizkikh temperaturakh 750-950°S v sul'fidno–oksidnoy srede, voznikayushchey pri sgoranii nizkokachestvennykh topliv, splavy dannogo klassa podvergayutsya intensivnomu korrozionnomu vozdeystviyu, chto privodit k prezhdevremennomu razrusheniyu otvetstvennykh detaley goryachego trakta i vykhodu iz stroya turbiny v tselom. Povyshenie koeffitsienta poleznogo deystviya turbin svyazano s povysheniem temperatury gaza na vkhode v turbinu, chto, v svoyu ochered', trebuet primeneniya novykh materialov i tekhnologiy, a takzhe modernizatsii sostavov promyshlennykh splavov dlya povysheniya nadezhnosti ikh raboty v protsesse dlitel'noy ekspluatatsii. Kniga prednaznachena dlya studentov, aspirantov, nauchnykh i inzhenerno-tekhnicheskikh rabotnikov v oblasti zharoprochnykh materialov dlya gazoturbostroeniya.
