Abstract
The present research investigates the thermal and corrosive behaviour of alumina-based ceramic coatings deposited on stainless steel grade 304 through the flame spray method. The microstructure of the coatings was examined using various techniques such as FESEM, EDS, and a 3D optical profilometer. The thermal conductivity of the coatings was determined by employing the hot plate method to calculate the temperature difference across the exposed coatings. Furthermore, an electrochemical test was conducted to evaluate the corrosion behaviour of the deposited coatings. The outcomes of the study reveal that the Al2O3–40%TiO2 coating exhibits significantly higher thermal and corrosive resistance characteristics in comparison to the stainless-steel substrate.
