Li Yongjun;Xiao Junfeng;Gao Song;Zhang Jiong;Gao Sifeng;Tang Wenshu;Nan Qing;Xi'an Thermal Power Research Institute Co.,Ltd.;  
The exposure curve for the experimental study on inspection of gas turbine blade by computed radiography was drawn to analyze crack in the blade.The results show that the cracks deeper than 0.6 mm and longer than 2 mm on the trailing and leading edge of gas turbine blades can be inspected effectively by using computed radiography.The visual effect of the cracks can be improved obviously by image processing technologies,so as to identify the cracks more clearly.
