Abstract: Ceramic matrix composites have attracted attention in advanced structural and tribological applications for several decades. Advanced structural ceramics are presently used in diverse tribological applications such as tips for ballpoint pens, precision instrument bearings and cutting tool inserts. Design and selection of ceramics for these applications require reliable data on the effects of temperature, load and environment on the tribological behaviour of these ceramics. In the present work, Al2O3-matrix composites reinforced with ZrO2 were produced with the aim of improving their toughness to extend their industrial applications. The Al2O3/ZrO2 composite was deposited on a steel substrate after several shots at different distances using a plasma focus device. Wear properties of Al2O3/ZrO2 matrix composites were evaluated from wear tests using chemical attack in aggressive acid conditions. The results show that the sample prepared with 30 shots at a distance of 2 cm gives the best results. Scanning electron microscope and X-ray diffraction techniques were used to analyze the microstructure and for phase assessment.
