THE EFFECT OF YTTRIUM ON HOT CORROSION BEHAVIOUR OF IN-939

Li Tiefan Duan Xuezhang and Pu Fijian (Instiitute of Metal Research, Chinese Academy of Scienles)  
The effect of yttrium on hot corrosion behaviour of east Ni-base superalloy IN-939 exposed to 75%Na_2SO_4+25%NaCl at 850℃ and 920℃, for 10hrs to 300hrs has been investigated by crucible test method in the present work. The kinetic curves obtained by measuring the weight losses and depths of penetration due to hot corrosion show that the addition of yttrium to IN-939 increases the resistance against hot corrosion of the alloy. The product of hot corrosion is studied by optical microscope, scanning electron microscope, electron microprobe as well as X-ray diffraction techniques. The morphology of corrosion product layer on the surface of IN-939 Y is different from that of IN-939 without yttrium. The corrosion product on the surface of 1N-939 alloys is found to be composed of chromium oxide and sulphide. The region just below is depleted in chromium. The corrosion product on the surface of IN-939 Y alloy consists mainly of Cr_2O_3 with some TiO_2, α-Al_2O_3 and traces of Y_2O_3, YCrO_3 and sulphides. But instead of depletion in Cr, a region depleting in Titanium, with internal oxides along grain boundaries and dispersed oxysulfide particles of yttrium and titanium is observed.
