Zirconia and Hydroxyapatite obtained by means of Plasma Spray deposition process are candidate coating materials for use in advanced industrial applications as in wear resistance and thermal barrier coatings and biomedical applications respectively. This paper deals with the test methodology for the analysis or evaluation of some physical and mechanical properties of zirconium oxide and hydroxyapatite coatings that have been applied by vacuum plasma spraying. Results of quantitative tests are presented based on the measurement of thickness, coating/substrate interface condition, porosity, coating microstructure, surface topography and microhardness. The main phases of the experiments, the choice of instruments and their application domain, the test methodology and procedure, specimen preparation and test conditions are discussed as applied to test cases. Paper includes a German-language abstract.
