Abstract

Wear is the main degradation of the combustor components in gas turbine power generation. One of the most vital components in a gas turbine is the combustion liner which is often observed with severe wear damage. In this study, the combustion liner was made from Hastelloy X (a nickel-based superalloy material). The degradation generally occurred at the mating surfaces of the combustion liner which consisted of the fuel nozzle and a transition piece. The purpose of this study was to determine and characterise the dominant wear mechanisms at two different contact surfaces (connected to stainless steel and Nimonic 263) after being exposed to 8,000 hours of run time at high temperature and vibration. The worn surfaces were analysed and the wear mechanism was discussed.
