TRIBOLOGICAL PROPERTIES OF Al2O3/ZrO2 SINTERED CERAMICS
Journal Title: Tribologia - Year 2019, Vol 283, Issue 1
Abstract
The paper presents mechanical and tribological properties of Al2O3/ZrO2 composite sinters with different proportions of Al2O3 and ZrO2 phases. These materials are commonly used in dry friction contact due to relatively low manufacturing costs of even complex shapes of products and the possibility of working at elevated temperatures. The tests were carried out by the ball-on-disc method at temperatures of 20, 150, 300, and 500°C. A ball made of Al2O3 was used as a counterpart. The results were compared with the following sintered mono-phase materials: Al2O3(alumina) and tetragonal yttria-stabilized ZrO2 polycrystallines (Y-TZP). The tests showed the significantly better properties of composite materials.<br/><br/>
