Study on the Effect of Wear Resistant Materials Applications in Reducing Wear Damage of Gas Turbine Combustor Components

Article Preview

Abstract:

Wear is the main problem in gas turbine combustor components. The mating surfaces experience surface degradation affected by wear damage. The main mechanisms of wear occurred on combustor components could be adhesive wear, abrasive wear, and fretting wear. Wear resistant materials such as Haynes 25 (L605) and Stelitte 6 were selected to be used in reducing wear damage especially on bull horn, transition piece and flow sleeve of combustor components. The reduction of wear on combustor components can be described as the extension of combustion inspection interval of a gas turbine. It is concluded that wear on combustor components can be reduced by the applications of wear resistant materials on the components.
