WO1995000682A1 - Process for removing corrosion from the surfaces of articles made of ferrous metals - Google Patents

Abstract

The process involves treating the surface, firstly, with an acidic corrosion converter of the following composition (grams per litre): ascorbic acid 10-35, complexing agent 2-7, water up to one litre, and subsequently with a passivating agent (a water-soluble corrosion inhibitor). The process facilitates the removal of corrosion from painted or unpainted surfaces and reduces the tendancy of the metal to become corroded again.
