Abstract

Oxides are chemically stable and wear resistant materials .
Because of these properties, they are often applied as protective
coatings in harsh environments. However, their chemical and
mechanical stability at high temperature in chlorine containing
environments is uncharted. These conditions are present in
waste-to-energy and biomass boilers in which the currently
available metallic and metal matrix composite coatings provide
unsatisfactory protection. To be effective in these conditions the
coatings should be chemically inert, erosion resistant and act as
environmental barriers. For this purpose, this research studies
the corrosion behavior and microstructural features of HVOF-
and APS-sprayed Al2O3-, Cr2O3-, TiO2-based coatings. Their
chemical stability was evaluated by high temperature corrosion
testing of self-standing coatings under KCl salt deposit at 550,
650 and 720 °C for the duration of 72 h.
