The results of experimental studies of the effect of the plasma sprayed alumina coating on the improved corrosion resistance of the heat-resistant ferritic
stainless steel (W.Nr. 1.4713, EN X10CrAlSi7) in the sulfuric acid are presented in
this research. In this investigation, the plasma spray process was employed on the
substrate of ferritic stainless steel with deposition of Al2O3 ceramic coatings with Ni5%Al as a bond layer. Two different coating thicknesses of 0.3 mm and 0.5 mm
were tested. The investigation was performed by electrochemical characterization
and weight loss method. Electrochemical characterization of corrosion behavior of
steel with and without ceramic coating was performed by: the open circuit potential
measurement (OCP), the linear polarization resistance (LRP) method, and the
Tafel extrapolation method. All electrochemical measurements were performed in
the sulfuric acid with a concentration of 0.25 mol/dm3
(pH 1.00). Weight loss
method was performed... with a duration of 240 h in the 38 wt.% sulfuric acid. Corrosion current densities obtained by electrochemical methods with the coatings were
between 3 and 4 % of the values of the samples without coatings. Nearly the same
results were obtained with the weight loss method. In both cases, these values are
similar to the porosity of the coatings.
