Abstract

Environment barrier coatings (EBCs) have been developed to protect metallic and Si-based ceramic
components of aerospace structures and turbine blades working under elevated temperatures and chemically harsh
environment. Mullite-alumina based coatings were deposited on low carbon steel by a relatively simple and low-cost
surface deposition technique based on the slurry spray technique (SST) developed for environmental barrier coating
applications. Corrosion test is conducted with a Corrosive medium of 6 M Na2SO4 solution prepared by adding
16.8g of Na2SO4 powder in 100 ml of pure water, magnetic stirred for 30 min. It has been found that the developed
coatings using SST demonstrate dense coating deposits with significantly less corrosion rate than that uncoated low
carbon which is comparable with that produced from traditional techniques.
