The interfacial toughness of two types of Al 2 O 3 -13wt%TiO 2 plasma-sprayed ceramic coatings on steel substrates-"conventional" and "nano"-has been measured using the Rockwell indentation method. The interfacial toughness of the "conventional" coating and the "nano" coating is found to be 22 and 4

Nanostructured Al 2 O 3 -13 wt.% TiO 2 coating was fabricated by plasma spray with nanocrystalline powders and the microstructures of the feedstock and the coating were characterized by means of XRD, SEM and TEM. It was found that three forms of substructure existed in the coating: one evolving from
Young's modulus and hardness were determined by depth sensing indentation in plasma sprayed Al 2 O 3 -13% TiO 2 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 test
