| Outline of Final Research Achievements |
The effects of shot peening (SP) on the wear performance of ceramics were investigated. Silicon nitride and partially stabilized zirconia plate specimens with and without SP were prepared. Then, ball on plate tests were carried out in air under dry conditions. The wear volume of the plate specimens with SP was lower than that without SP. The wear volume was lower because of the compressive residual stress that was introduced by SP. This result indicates that SP is an effective method to reduce the wear volume of ceramics, thus making it suitable for use as a slide member.
