Characterization of ceramic films and interfaces by electron microscopic and spectroscopic techniques
In this study, Auger electron spectroscopy (AES) in combination with inert gas ion milling and cross-sectional transmission electron microscopy (XTEM) were employed to investigate the chemical and microstructural characteristics of a TiN film on a M50 steel and the film-substrate interfaces formed during ion plating at 100 C and 500 C deposition temperatures. The results of both analytical techniques indicated that the coating produced at 100 C was composed of a thin Ti layer (approximately 1000 A) and a thick TiN layer. Upon vacuum annealing at 500 C for 45 minutes, it was found that the Ti rich interlayer was transformed into a TiC phase. The coating produced at 500 C consisted of a thin TiC and a relatively thick TiN layers. Ion plating as well as post vacuum annealing at 500 C resulted in grain growth and reduced defect density. 11 refs., 8 figs.
