Abstract
Paper presents selected properties of a kind of alumina toughened zirconia (ATZ) composites manufactured by the method which utilize reactive sintering process. Products made by means of this process show many perspective properties which could improve their usefulness as machinery parts materials. These properties comes from much finer microstructure than this obtained in typical AZT or TZP (tetragonal zirconia) materials. Special advantages mentioned materials showed in tribological applications connected with sliding cooperation without any lubrication at temperatures exceeded 300 °C like rolling elements of machinery or parts subjected to intensive abrasion. Another potential field of application is area when working elements are subjected to stable load under critical value. Actually, in ever known oxide materials at such conditions slow crack propagation phenomenon occurs. In a new type of ATZ materials this phenomenon could be distinctly limited or even stopped. In the paper we present a results of investigations which confirm high level of useful properties detected in a new type of ATZ composites.
