Abstract
A gas turbine is operating under high temperature and pressure, and its start-stop cycles generally fall on peak demand. Therefore, the main components of the gas turbine frequently get damaged that involves high costs. But diagnosis and maintenance of main components is accomplished by maker, The cost of diagnosis and maintenance is required excessively by maker. In this research, we present standard about refreshing product or waste product through estimation about gas turbine bucket coatings. Specially, present 24,000 times, presented standard that evaluate propriety of regeneration period after use.
