摘要：
In this study, the corrosion behaviour of decorated Al2O3 coating with Cu was investigated on AISI 304L stainless steel substrates. Plasma spray technique was employed on substrate with the deposition of Al2O3 ceramic powder. The copper decoration technique was used to study the types of defects in coatings. Potentiodynamic polarization measurements were also employed to determine the corrosion behaviour of Al2O3 coating and decorated Al2O3 coating with Cu. The microstructure of coating was investigated by means of an optical microscopy. In addition, X-ray diffraction of the used powders and coatings was utilized. It was obtained that the passivation range of Al2O3 coating decorated with Cu increased considerably.
