Indentation properties of plasma sprayed Al2O3–13% TiO2 nanocoatings
چکیده انگلیسی

Young’s modulus and hardness were determined by depth sensing indentation in plasma sprayed Al2O3–13% TiO2 nanocoatings. Results were compared to conventional coatings and the relevance of the nanostructure was analyzed. An indentation size effect was observed. Data provided by indentation tests at different maximum loads were used to estimate size-independent hardness and elastic modulus. Enhanced properties were observed in the nanostructured coating compared to the conventional one. Partially melted zones in the nanocoating, which act as reinforcements in the ceramic matrix composite, are likely responsible for the enhancement.
