Abstract
The dispersion of Vickers microhardness values of Plasma Sprayed (PS) ceramic coatings is often quite high, due to unhomogeneous phase distribution, defects and porosity. Specific experiments have been planned and executed on Plasma Sprayed Partially Stabilised Zirconia (PSZ) coatings, in order to analyse the variation of hardness along coating thickness and the dependence of the measurements on test load and porosity level. A contribution to a methodology and a preliminary protocol definition for measurement and statistical analysis, to be followed to obtain significant and repeatable results, have been studied and proposed. Consequently, microhardness test load, coating test area and statistical analysis technique to be applied, have been studied, validated and proposed.
