materials for compressor blade
yoqIJI yeP,on collloo压气机叶片材料(materials for compressorblade)压气机叶片工作在空气氧化锈蚀的环境中,必须有良好的抗氧化锈蚀的能力。在海洋条件下工作时,还要有抗海水腐性的能力。动叶片还需承受很强的离心应力和振动应力等,要求有高的强度、良好的抗振性能、韧性和抗疲劳强度。 现有的重型徽气轮机压气机叶片的工作温度低于500℃,广泛采用含12%~13% Cr的马氏体不锈钢制造动叶片和静叶片.这是由于,12%~13%Cr钢不但有足够的强度,良好的抗氧化腐蚀性能外,还有优良的抗振性能。航空嫌气轮机中为了减轻重量,早期曾广泛采用铝合金做叶片,但由于强度与抗腐蚀性能均较差,现已被俄合金取代。傲合金不仅强度好、较轻,而且抗海水腐蚀的能力强,但高温性能较差,常用作工作温度低于300~400℃的叶片材料。航机改型燃气轮机的压气机叶片一般用铁合金或含Cr不锈钢制造。
