Abstract
The residual stress and strength characteristics of partial stabilized zirconia induced by shot peening with soft aluminium particles were evaluated by the X-ray stress measurement method. It was confirmed that a compressive residual stresses ranging from 250 to 340MPa were induced on to the plates of partially stabilized zirconia by the soft shot peening treatment. It was also confirmed that the modilation of surface defects and surface roughness after shot peening with soft aluminium particles was insignificant. Furthermore, the bending strength and the Weibull modulus of the shot peened partially stabilized zirconia was improved by compressive residual stresses.
