TiN films were deposited on Inconel 600 by PACVD method using a gaseou
s mixture of TiCl4, N-2, H-2 and Ar, and their pitting resistance and
mechanism in 100 degrees C NaCl solution were investigated. Anodic pol
arization measurement of TiN-coated Inconel 600 was compared with that
of bare Inconel 600. TiN-coated Inconel 600 has a higher E(np) and a
lower pit depth than bare Inconel 600. It also shows a smaller pit asp
ect ratio due to the concentration of the corrosion in the Inconel 600
contacted with the TiN film. When the Inconel 600 has a rough surface
, E(np) decreases and the pit density increases to a great extent. How
ever, E(corr), pit depth and pit aspect ratio are not affected.
