Abstract
Industrial gas turbines, aircraft gas turbines, steam turbines and coal-utilization turbines, when operating under particulate flows, are exposed to erosion and performance deterioration. This paper describes an experimental method used to find the erosion behavior of superalloys and coatings subjected to gas-particle flows at high temperatures. The erosion behaviors are investigated experimentally at high temperatures using a specially designed erosion wind tunnel. The erosion results show the effects of velocity, temperature and impact angle on the erosion rate.
