400KeV Ag+ ions were irradiated to the (100) surfaces of 9.5m% Y2O3 stabilized ZrO2 with the doses ranging from 5×1015 ions/cm2 to 5×1017 ions /cm2 at room temperature in order to investigate the correlations between the state of implanted Ag and the suppression of crack initiation.<BR>1) Ag precipitated as particles in orienting the (200) face of Ag. The sizes of the Ag particles were ranging from 2nm(5×1016ions/cm2)to 11nm (5×1017ions/cm2).<BR>2) Knoop hardness of the surface of ZrO2 increased by about 20-30% by Ag+ ion-irradiation at the doses less than 5×1016ions/cm2 and decreased at the doses larger than 1×1017ions/cm2.<BR>3) Vickers indentation crack at a loads of 0.25N was completely suppressed in the surface of ZrO2 irradiated to a dose of 5×1017ions/cm2.<BR>4) The suppression of the crack initiation may be ascribed to the influence of the nanometer composite layer containing max. 23at% Ag.
