| Summary: | 碩士 === 大同大學 === 材料工程學系(所) === 95 === A fluidized bed carburizing (FBC) process was developed to see the effects on surface modification of commercial purity titanium (CP-Ti) and Ti-6Al-4V (Ti-64) alloy. The performance of a patented molten salt carburizing (MSC) process was also cited in comparison. A mixture of diamond, graphite and rutile were identified to form on the outermost surface for both processes. The major product at the near surface layer for both processes was carbon deficient titanium carbide TiC1-x. The lattice constants (ao) of TiC1-x and the associate stoichiometric ratios (1-x) were obtained by Nelson-Riley approach and interpolation, respectively. The enhancement of surface hardness was more pronounced by employing FBC process.
