Oving High Temperature Corrosion of the Steel Pipe High Pressure Boiler Coated By Titanium Carbonitride

Author(s): W Aperador, J Bautista-Ruiz and E Ruiz

In this paper, the corrosion resistance of steel high pressure boiler steel pipe (ASTM A335) is studied coated and uncoated of Carbo-Titanium Nitride (TiCN), grown on substrates 316 steels using cosputtering r.f. The coatings were studied by potentiodynamic polarization curves Tafel using corrosive salts (vanadium pentoxide V2 O5 and Na2 SO4 sodium sulfate). The layers of Ti-C-N were grown varying the nitrogen flow to study its influence on the high temperature properties of these coatings, in addition to the bias voltage variation. Through of the technique of X-ray diffraction, it was found formation titanium carbonitride phases with orientation (200) and (111) and ESD spectroscopy shows an increase in the content of C and Ti with increasing nitrogen flow decreasing for high flows with -50V Bias. It found a decrease in the corrosion rate for the three coatings, additionally it decreases with increasing atomic nitrogen content.
