Paper deals with testing of mechanical properties of plasma sprayed coatings TiO2 by Depth Sensing Indentation performed on measuring system NanoTest 600™. The NT600™ is a modular measuring instrument with unique design, which applies the loading force in horizontal direction. The platform can measure and evaluate hardness, elastic modulus, adhesion, wear, fracture and also dynamic properties. In the last years the new plasma spraying technology of ceramic and ceramic-metal materials has became as very convenient technique in many industrial and reconstruction processes. The investigated samples of plasma sprayed coatings were prepared in Institute of Plasma Physics of the Academy of Sciences of the Czech Republic. The goal of this paper is to contribute to deepening the knowledge in local distribution of mechanical properties in plasma sprayed coatings, especially of hardness and elastic modulus.

APS Spraying of MgO and CeO2 with WSP
Neufuss, Karel ; Dubský, Jiří ; Kolman, Blahoslav Jan ; Chráska, Pavel ; Brožek, Vlastimil ; Boháč, P.
Some oxide ceramics with high temperature meltung points are very difficult to spray.Paper reports on successful spraying of MgO and CeO2, both with Tm>2700 řC.Water stabilized plasma (WSP) with high enthalpy/high temperature plasma stream was used.
