Corrosion Inhibition Studies Using Polyoxometalates

2006 by bquimby

Several methods are currently in frequent use to prevent the corrosion of metal surfaces. Electroplating copper or chromium onto metal surfaces, usually steel or aluminum alloy for most commercial applications, is one way of inhibiting corrosion. This method can be toxic, especially when using chromium. Another way to fight corrosion is by using a sacrificial anode, but this method requires the replacement of the anode as it is consumed. Polyoxometalates (POMs) are growing in popularity as corrosion inhibitors as more studies are being conducted on their electrochemical and adsorptive properties. POMs are large metaloxygen clusters usually containing tungsten or molybdenum. POMs are desirable for corrosion inhibition because of their ability to accept multiple electrons and still maintain their structure and surface adsorption characteristics.
