A. Hello Shoaib,

Variation in the nitrogen gas level gives change in color of Ti coating. TiN is generally gold in color, if you go up to 500 sccm of nitrogen with lowest bias you get a reddish golden color. including carbon ^chrome in Ti material, i.e., TiC ^TiCr with only Nitrogen gas in coating gives Blue color.

A. Sorry Shoaib,
I mentioned C in TiC as carbon, please correct it, it's Chrome.
