Tribology in Industry, Vol 46, Iss 1, Pp 39-47 (2024)
An alumina-toughened zirconia (ATZ) material, fabricated using a procedure consisting of the common sintering of two different zirconia powders, was tested using the ball-on-disc method in a temperature range between 20 and 400 °C. Tetragonal zircon
