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</dc:description><dc:description xml:lang="sl">Med uporabo plinskih turbin (GTE) se v lopaticah kopičijo napake. Te so posledica statičnih napetosti zaradi centrifugalnih in termo-cikličnih napetosti. Ker plinske turbine obratujejo v spremenljivih razmerah, časa eksploatacije ni mogoče upoštevati kot zanesljivega parametra za določitev preostale trajnostne dobe. Na nesrečo v mnogih primerih, ko je GTE ustavljena zaradi vzdrževanja, niso poznane termične razmere prejšnje uporabe lopatice. V tem sestavku predstavljamo novo metodo za določanje preostale trajnostne dobe za lopatice s prekritjem. Ocena dolgotrajnega zmanjšanja trdnosti je izvršena na podlagi ekvivalentne temperature uporabe Tspodajeq, znanega časa uporabe tau in statičnih napetosti sigma</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-S191DNTO"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-S191DNTO" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-S191DNTO/74dcddde-cb05-46f2-b4e1-e8a110279065/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-S191DNTO/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-S191DNTO" /></ore:Aggregation></rdf:RDF>
