SURFACE TREATMENT FOR ZIRCONIA BASED MATERIALS

摘要

The invention is directed to a method by which the bonding strength between zirconia-based materials and other materials can be improved, and to zirconia-based materials obtainable by this method and which have improved surface properties. According to the present invention there is provided a method for increasing the bond strength between stabilized zirconia and another material, wherein said stabilized zirconia comprises ZrO2 and at least one stabilizing compound. The method of the invention results in stabilized zirconia which has an improved bond strength with other materials, which bond strength is stable with time. The surface modified stabilized zirconia of the invention can be used in prosthetic restorations, implants, solid electrolytes, fuel cells, oxygen sensors, cutting abrasives, or electrical insulators.
