Abstract

Corrosion resistance behaviour of Potentio-dynamic polarization and electrochemical impedance spectroscopy measurements are used to investigate the effects on the corrosion resistance behaviour of Sm₂Co₁₇ in Cl^-1 containing environment. The experiments were conducted in 3.5wt% NaCl solution at 25 C for one day. During the 24hours immersion, the corrosion current of Sm₂Co₁₇ magnet changed from 5.679x10^-6 to 1.03x10^-5 A/cm² and there was no apparent changed in magnetic properties measured at 25 C after corrosion tests. Microstructure study results showed the material response to pitting corrosion which alternately emphasized the importance of surface engineering.
