2.1 Effect of N+ Ions Implanted on Electrochemical Property of 316 s.s.,Super-pure Aluminium and 6061 Aluminium Alloy Ma Yan Lu Haolin Yang Qifa Yang Hongguang 316 s.s., super-pure aluminium and 6061 aluminium alloy are three materials widely used in engineering. For improving some of their mechanical properties, such as self-welding, friction and fretting resistence properties, surface processing is employed sometimes, for example, ion implantation, thermal spray coating, nitridation. Ion implantation is an advanced method of material surface treatment. This report describes the effect of corrosion resistance on three materials above mentioned by N+ ions implanted. Firstly, the samples were implanted with 160 keV N+ ion and the total dose was 15×1017 cm-2. The method of controled voltage was used to measure the electrochemical property. The corrosive medium was 0.5 mol·L-1 H2SO4 and reference electrode was calomel electrode. The anodic polarization curves of materials implanted and unimplanted were obtained by Model 350A corrosion measuring instrument(Fig. 1, 2,3).
