Fatigue Sensitivity of Y-TZP to Microscale Sharp-Contact Flaws

Published

Author(s)

Yu Zhang, Brian R. Lawn

Abstract

The strength degrading effects of sharp-contact damage are examined for Y-TZP ceramic plates bonded to a plastic substrate. Microscale contacts are made with Vickers and Berkovich diamond indenters at low loads (0.01 N to 10 N) in the ceramic lower surfaces prior to bonding to the substrates. The indentations remain in the subthreshold region, i.e. without visible corner radial cracks, over the lower region (
