【 摘 要 】

Turbine blades are core components in turbine. It is of great significance to diagnose the blade failures at early stage and regularly inspect them at run time. Based on the analysis of blade failures, a comprehensive application summarize of different non-destructive testing techniques in blade inspection was made in this paper. The non-destructive testing techniques include visual testing, liquid penetrant testing, magnetic particle testing, radiological testing, conventional ultrasonic testing, ultrasonic phased array testing, eddy current testing and metal magnetic memory testing. The applicability and limitation of different methods were demonstrated through comparison and analysis.
