Abstract

In this research, an investigation was conducted to study the fly ash particles associated with the erosion behavior of alloys and coatings that are widely used in gas and steam turbines. The erosion behavior of many alloys and protective coatings has been investigated experimentally at high temperatures using a specially designed wind erosion tunnel. The erosion results show the effect of velocity, temperature, and impact angle on the erosion rate.
