The article discusses the use of laser processing to extend the service life of single-crystalline (SX) turbine blades. Various damage mechanisms still occur during service life despite the use of high-end materials. It is of critical importance that the repair procedures do not influence the macrostructure of the base material in order to avoid deterioration of the mechanical properties. The key to lifetime extension of single crystalline blades is thorough inspection.
