Characteristics of the Structure and Corrosion Resistance of New Elaborated Coatings for Energy Industry

Article Preview

Abstract:

The material conception of manufacture new coatings with high dispersion phases are presented. The coatings were obtained by thermally sprayed technology. The results of the hot temperature oxidation test of the new elaborated coatings were analyzed and compared. The reaction rate constant was calculated. The mass chance as a function of spallation process were recorded The microstructure of coatings was obtained by LM microscopy. After corrosion tests, the presented coatings were investigated in respect of the changes on the surface like: pits, cracks as well as oxidation layers. The results have been stored using digital imaging techniques, Nikon and PC. The presented coatings can be used to basic protection to wear and corrosion condition in the energy boiler.
