The adhesive forces and the specific surface energy of ceramic material surfaces are very important for further tribological and biomedical applications of ceramics. Partially stabilized zirconia (zirconium oxide) is popular for manufacturing various medical products. ZrO2 stabilized by Y2O3 with additions of 5 wt% alumina was produced by slip casting method with a subsequent sintering. Structure and chemical composition of ceramic surface were analysed by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy. The adhesive forces were measured by means of atomic force microscopy (AFM) method. Parameters of specific surface energy show some range of values. Results demonstrate the importance of evaluation not only total surface specific energy but its local parameters in the points of additives concentration on the surface of material.
