摘要：
The surface properties of mechanical parts can be improved through Duplex surface treatments, which consist in the combination of two different treatments, leading to a higher surface quality of the treated material by adding the advantages and removing the disadvantages of these treatments. An alloyed steel that is used in mechanical and automotive industry was duplex treated consisting of gas carburizing and surface induction quenching. The corrosion behaviour of the untreated steel, the carburized steel and the duplex treated steel was investigated by liniar polarization scan in a sodium chloride solution. The structure of the Duplex and non-Duplex samples was investigated by optical microscopy.
