Inhibition of Al Alloy Corrosion by Chromates

Abstract

So what’s the big deal about Al corrosion? A recent literature search indicated that about 45 papers have been published in J. Electrochem. Soc. alone over the past five years in the area of Al and Al alloy corrosion (not including work related to batteries and microelectronics). Numerous symposia on localized corrosion and light alloy corrosion have taken place over this time period with large numbers of presentations on the mechanisms of localized corrosion in structural Al alloys and its inhibition by chromates and environmentally friendly inhibitors. Interest in these topics has existed for a long time, but the recent flurry of activity was initiated by the U.S. Air Force (USAF) around 1996.
