摘要：

A high temperature ion implantation method, employing a high current density beam (e.g. 500-mu-A cm-2) of nitrogen ions was used to modify the near-surface microstructure of Ti-6Al-4V. A systematic study was performed with nitrogen implantation at temperatures from 400-degrees-C to more than 1000-degrees-C, and to a range of doses from (0.1-1.0) x 10(18) N2+-N2+-N+ cm-2. Microstructure characterization by Rutherford backscattering spectroscopy (RBS) and glancing incidence X-ray diffraction (GID) was performed to determine the nitrogen distribution and compound formation. RBS analysis showed enhanced nitrogen penetrations for the 800-degrees-C and 1000-degrees-C implantations compared with implantations at temperatures less than 600-degrees-C. GID indicated TiN and Ti2N concentrations were the greatest for the 800-degrees-C implantation treatment.
