A chromate conversion coating formed on an article in an acidic chromating bath in reaction with a metal surface on the article, such as cadmium or zinc, is stabilized by subjecting the coating to an alkaline bath having a pH in a range between 11 and 12, immediately upon removing the article from the chromating bath and without first rinsing the article in water. The stabilized coating exhibits resistance to damage during rinsing and drying operations.
