Abstract

In order to clarify the difference in the texture formation of the TiN films deposited on various steel matrices, TiN ceramic coating was done on the surface of a polished (011) [100] single crystal of silicon steel, grain oriented silicon steel, SUS 304 and SUS 430 stainless steel sheets and interstitial free (IF) steel sheets. Pole figures of dual textures of the TiN films and related steel matrix samples were measured simultaneously using a solid state detector (SSD) auto pole figure apparatus.
{111}TiN pole figures of the TiN films deposited onto the surface of a (011) [100] single crystal of silicon steel and grain oriented silicon steel sheet showed the dominant texture of (111) [110] orientation, whereas the {100}Si-steel pole figure of the silicon steel matrices showed the dominant texture of (011) [100]. Subsequently, {111}TiN pole figure of the TiN films deposited on the surface of the SUS 304 stainless steel sheet showed a weak texture of (111) [110], and {100}Stainless steel pole figure of the SUS 304 stainless steel sheet showed the texture of (112) [111]. Moreover, the {111}TiN pole figure of the TiN films deposited on the surface of SUS 430 stainless steel showed the texture with a very weak {111}TiN plane and that of IF steel sheets showed no preferred orientation.
From these results, it is concluded that texture formation of TiN films takes place preferentially when these films have a good coherency with steel matrices.
