摘要：

The wear of two ceramic materials containing partially stabilized zirconia is studied under unlubricated friction against steel. The first material, with ZrO2 and 3 mol % Y2O3, was obtained by cold isostatic pressing and sintering. The second material, comprising ZrO2 and 4 mol % Y2O3, was fabricated by additional hot isostatic pressing. The samples of both materials were fabricated with high and low values of fracture toughness. The samples with high fracture toughness are found to wear more intensively. This fact can be explained by surface micro-cracking during braking as a result of phase transformations.
