Corrosion resistance study of grey cast iron implanted with C, N, Cr and Cu ions

[摘要] This article deals with the corrosion resistance of gray cast iron implanted with C, N, Cr and Cu ions in sodium chloride solution and sulfuric acid solution. The potentiodynamic research was conducted in atmosphere, simulating corrosion conditions: in 3% sodium chloride solution and in 0,1 N sulfuric acid solution. Potentiodynamic curves were obtained and surfaces of samples were observed. The research proves that the implantation of ions with N and Cr leads to an increase in the corrosion resistance of cast iron in sodium chloride solution, and the implantation of ions with N and Cu leads to increased corrosion resistance in sulfuric acid solution.
