Graphite and aluminum corrosion

WebIn general, aluminium alloys are characterized by a relatively low density (2.7 g/cm3 as compared to 7.9 g/cm3 for steel), high electrical and thermal conductivities, and a resistance to corrosion in some common environments, including the ambient atmosphere. WebThink of the corrosion potential if you put a big hunk of graphite on a small piece of magnesium. In a galvanic couple, the metal higher in the series (or the smaller the …

They … WebThe corrosion results in the break-up of bulk metal to metal powder. Corrosion occurs as a graphite layer is deposited on the surface of the metals from carbon monoxide (CO) in the vapour phase. This graphite layer then goes on to form meta-stable M3C species (where M is the metal) that usually moves away from the metal surface.

WebDec 2, 2013 · Graphite is not corrosive in itself towards aluminum, but in the presence of chloride ions (such as from sea-water or marine atmosphere) it can cause galvanic (bimetallic) corrosion to occur.
