Abstract
There is a high demand for eco-friendly, effective, and high performance corrosion inhibitors for industrial applications. Thus, the corrosion property of aluminum alloys was studied in linseed oil. Potentiodynamic polarization and weight loss analysis were used to study the corrosion inhibition mechanism of the linseed oil. The linseed oil showed the highest inhibition efficiency of 87.01% at 1000 ppm. A high efficiency of 86.03% was achieved even after 24h of exposure. The potentiodynamic polarization test showed that the linseed oil is a mixed-type inhibitor. The surface morphology of the uninhibited and inhibited specimens examined by a scanning electron microscope.
