Aluminium oxide - Wikipedia

WebThe corrosion resistance of aluminum is due to its tendency to form a compact oxide layer over the surface. The oxide formed offers a high resistance to corrosion. The normal surface film present in air is about 1 nm thick. The film thickness increases at the elevated temperature. The film growth is more rapid in water than in oxygen. WebIn the pH range 5.7 to 6.7, aluminium hydroxide species dominate, including Al (OH) 2 + and Al (OH) 2 +, and then Al (OH) 3.
