摘要：

This work presents the data on the corrosion resistance of titanium after Ca and/or P ion implantation with a dose of 10(17)/cm(2). The Ca-,(+) P+ ion energy was 25 keV. The corrosion resistance was examined by electrochemical methods in a simulated body fluid at a temperature of 37 degreesC. TEM was used to investigate the microstructure of implanted layers. The chemical composition of the surface layers was examined by XPS and SIMS. The results of electrochemical examination indicate that the P and Ca + P ion implantation into the surface of titanium increases its corrosion resistance. Samples implanted with Ca showed pitting corrosion during anodic polarization. The breakdown potentials were high (2.5-3 V). (C) 2001 Elsevier Science Ltd. All rights reserved.
