Abstract：In order to increase the corrosion resistance of aluminum, this study used DC plasma nitriding in the mixture of (PN2/PH2 = 4/1) plasma at the temperature of 673 K and 723 K for 8, 12 and 20 hours After some surface analyses such as SEM,EDX and XRD,it was found that the growth of the created layer on the surface of samples increased with treatment time and temperature For investigating the corrosion resistance of sample, this study used potentiodynamic polarization test in 3.5% NaCl solutionThe result showed that the corrosion behavior of samples depended on the quality of AlN layer,and the highest corrosion resistance achieved at 723 K and 20 hours
