摘要：

The surface-modified layer of calcium-ion-implanted titanium and dissolution of calcium ions from the layer into nitric acid (pH - 0.99) and phosphate-citric acid buffer (pH 5.2) solutions at 310 were characterized using Auger electron spectroscopy. Results showed that the surface-modified layer consisted of three layers while calcium existed in whole depth of the surface-modified layer. The calcium ions eluted into both solutions by the dissolution of the surface-modified layer itself and the dissolution of calcium by the diffusion through the surface-modified layer.
