摘要

The inhibitive action of potassium iodide (KI) on the corrosion of Al-Si/SiCparticulate composite in 3.65% NaCl solution was investigated using gravimetric andpotentiodynamic polarization techniques at 298K. The results showed that KI in NaClaluminiumalloy/SiC composite environment decreased the corrosion rate at allconcentrations considered. Inhibitor efficiencies (IE) of 97.17, 97.34 and 97.57% with 0.5 g/vaddition using gravimetric method were achieved at 92, 196 and 288 h of exposure timerespectively. The IE from the potentiodynamic polarization method in both conditions wassignificantly enhanced. The high resolution scanning electron microscope (HRSEM) forsurface morphology of as-corroded uninhibited condition showed pits and cracks formationthan as-corroded inhibited condition. The additions of KI as corrosion inhibitor indicates ahigher potential value, IE and polarization resistance with decreased in current density. Thetwo methods employed for the corrosion assessment of the composite was in agreement andmixed-type corrosion exists which followed Langmuir adsorption isotherms.
