Nitriding Based Plasma for Some Alloys for Corrosion Protection in Saline Water at Different Temperatures

Authors(2) :-Khulood A. Saleh, Ahmed H. Al-Jobouri

In this research a new physical deposition methods has been chosen, nitriding based plasma is an economical method to improve the corrosion resistance of three types of alloys (CS1045,CS1137and Al5083 alloy), CS means Carbon Steel & Al means Aluminum alloys. The morphological analysis was carried out using  atomic force microscopy (AFM).

 

The corrosion protection efficiency inspection of each specimen in saline water (3.5%NaCl) at different temperatures (25, 35, 45 & 55)  have been evaluated using potentiostatic techniques with three electrodes cell. Nitride ion is deposited on the three alloys and then we studied the extent of this corrosion resistance. The results showed that deposition of N2 gas as nitride ion caused to protection efficiency reached to72.77% for CS1045,61.93% for CS1137 and 90.28% for Al5083  respectively in 25 . Change in the enthalpy of activation & entropy of activation were evaluated. Apparent energies of activation have been calculated for the corrosion process of uncoated  and coated alloys by nitriding based plasma technique in saline water (3.5% NaCl).
