抄録

A partially stabilized zirconia (PSZ) was implanted with N+ ions and the wettability against the Zr-47 mass%Cu alloy was measured by the sessile drop method. Surface characterization of the implanted 3Y-PSZ was performed using XRD and XPS.<BR>The contact angle of PSZ against the Zr-47Cu alloy at 1273 K was improved from about 60 to 45 degrees by the implantation. The results of XRD showed that tetragonal phase of zirconia was converted to a monoclinic phase by the implantation. XPS indicated that the surface of the implanted PSZ was more metallic as compared with the inside of the material. This implies that zirconia was reduced by N+ ion implantation. The improvement of wettability is considered to be attributable to the formation of the metallic and active layer up on the surface.
