Scanning electron microscopy and x-ray diffractometry are used to study the microstructure, hardness, density and the wear resistance of sintered composites with a magnesium alloy AZ91 matrix reinforced with ZrO2 particles prepared using hot pressing. It is shown that ZrO2 particles are agglomerated in any condition. In addition to zirconia, the structure contains Mg and Mg17Al12. Particles of ZrO(2)facilitate an increase in hardness and whose oxidation and abrasive mechanisms predominate.
