Paper Title:
Performance of Thick TiN Composite Coating as High Heat Resistant TBC
  Abstract

Titanium nitride (TiN) coating has excellent properties and has been already used in the various field of industry. But TiN film has problems in the formation process: i.e., low deposition rate and poor thickness of the film. TiN thick coatings can be formed by means of the gas tunnel type plasma reactive spraying in a short time operation. In this study, the fundamental characteristics of this method were investigated by measuring the properties of the titanium nitride (TiN) coatings formed on the traversed stainless steel substrate. Consequently, TiN coatings of 200µm thickness were obtained at P=27kW, within t=5s, and some coating characteristics which depend on the spraying distance, the environmental gas, traverse number etc. were clarified. And the performance of TiN thick composite coating was discussed as a heat resistant TBC.
