Abstract:
Disclosed are methods for treating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods include contacting the metal substrates with a conditioning composition including a free fluoride source and then depositing a pretreatment composition including a Group IIIB and/or IVB metal on a portion of the substrate contacted with the conditioning composition. Also disclosed are electrophoretically coated substrates treated by the methods.
