  TiN film was coated on the internal face of racetrack-type ceramic pipe by
three different methods: radio-frequency sputtering, DC sputtering and DC
magnetron sputtering. The deposition rates of TiN film under different coating
methods were compared. According to the AFM, SEM, XPS test results,these
properties were analyzed, such as TiN film roughness and surface morphology. At
the same time, the deposition rates were studied under two types' cathode, Ti
wires and Ti plate. According to the SEM test results, Ti plate cathode can
improve the TiN/Ti film deposition rate obviously.
