Abstract
The use of aluminium alloy is increasing significantly in recent 5 decades. Many products made of aluminium are available in market. Aluminium widely used as building material and building construction. A series of experiments and measurements have conducted in relation to cases where the aluminium alloy make contact and make crevice gap to steel. The variable of experiments including the aluminium making contact to steel, make the gap of 0.21 mm and of 0.43 mm. The corrosion rate of Aluminium 1100 found 485.07 MPY. The interface potential of aluminium is -709 mV VS Cu/CuSo4 and Medium Carbon Steel (MCR) is – 698 mV VS Cu/CuSO4 when in contact, and the interface potential when in gap of 0.43 mm is – 610 mV VS Cu/CuSO4 for Aluminium 1100 and -754 mV VS Cu/CuSO4 for Medium Carbon Steel. When aluminium 1100 in contact with steel in chloride environment, the interface potential of steel would polarized and make it being more anodic. The gap width influence the surface potential.
