Abstract: A sealing process includes impregnating an oxide layer of an anodized metal with a corrosion inhibitor by contacting the oxide layer with a first corrosion inhibitor solution at a first temperature and sealing the impregnated oxide layer of an anodized metal by contacting the impregnated oxide layer with a second corrosion inhibitor solution at a second temperature, wherein the first corrosion inhibitor solution has a corrosion inhibitor concentration greater than the second corrosion inhibitor solution and the first temperature is less than the second temperature.
