These defects result from both the static stress caused by the centrifugal forces and by the thermo-cyclic stress. Since gas turbines usually operate under variable conditions, the time of exploitation cannot be taken as a reliable parameter for a determination of the remaining lifetime. Unfortunately, in many cases, at the moment when a GTE is stopped for maintenance, the thermal conditions of the previous exploitation of the blades are unknown. In this presentation a new method of determining the remaining lifetime for coated blades is considered. A long-term strength-decay evaluation is carried out on the basis of the equivalent exploitation temperature Tsubeq, the known exploitation time tau and the static stresses sigma"},{"@xml:lang":"sl","#text":"Med uporabo plinskih turbin (GTE) se v lopaticah kopičijo napake.
