THE EFFECT OF PH AND TEMPERATURE ON CORROSION RESISTANCE OF TIO2 COATED AISI 316L STEEL

Author

Abstract
A thin film of titania (TiO2) was deposited onto AISI 316L steel using physical vapour deposition (PVD). Coating thickness was measured using Elecometer instrument and it was (150µm).Corrosion resistance to (H2SO4,HCl, H3PO4, and HF) acids with (2&4) pH, and to (NaOH, KOH,Ca(OH)2, and NH4OH) basis with (10,12) pH, of coated specimen was measured at temperatures ranges from (25-190) Co by weight loss method. It has been found that TiO2 coating largely enhance corrosion resistance of steel alloy especially at high temperatures.
