Abstract

The corrosion properties of amorphous Mo-Si-N and nanolayered Mo-Si-Nn/SiC coatings on Fe37 low carbon steel were studied using electrochemical polarization measurements in 1 N sulfuric acid solution. A decrease in both critical current density for passivation and minimum current in passive state was observed in annealed nanolayered Mo-Si-N/SiC coating compared to each of its constituents alone as single layer coating. Only slight increase in critical current density was observed in Mo-Si-N coated sample after annealing.
