简介:气轮机运行过程中,高温含尘气体会对气轮机叶片表面产生不可避免的冲蚀与磨损,不仅破坏气动性能,严重时还可能使构件及设备失效,导致经济性和可靠性均下降。在自行研制的气固两相热态冲蚀实验风洞实验系统中,通过对比基材钢(1Cr12Mo、X20Cr13、2Cr12NiMo1W1V、GH738)在不同温度、不同冲角和不同粒径石英砂颗粒冲蚀下的冲蚀率变化,在本实验条件下,得出以下结果:200~300℃时,1Cr12Mo相对于其他3种基材,抗冲蚀性最好,400℃时2Cr12NiMo1W1V与GH738相对其他2种基材抗冲蚀性较好,而500℃时,从整体来看2Cr12NiMo1W1V比GH738抗冲蚀性好。
