Abstract
Description
Claims (1)
- 2. A method for treating ferrous metal surfaces which comprises spraying the aqueous phosphating solution as claimed in claim 1 on the ferrous metal surface to be treated, and maintaining the aqueous solution in contact with the metal surface for a period sufficient to effect degreasing thereof and the formation of a phosphate coating thereon.
