摘要：

In an attempt to improve the oxygen surface-exchange coefficient of yttria stabilized zirconia, we have implanted the surface with low-energy (10 keV) V and W ions. The surface concentrations of V and W under various annealing and sputtering conditions have been measured by low energy ion scattering. In addition, O-18-isotope tracer measurements have been carried out to examine the oxygen exchange behavior. For certain conditions, the oxygen uptake is enhanced. (C) 2002 Elsevier Science B.V.
