Near-neutral pH pickling solutions on polymetals |
| abstract |
The present invention proposes a near-neutral pH pickling composition for removing oxides from metal surfaces, including heat-treated steel. The pickling composition comprises a) a water-soluble organic or inorganic nitro compound in which the central N atom has an oxidation state of 3+; b) a polarizer for the nitro compound, wherein the polarizer comprises at least one of a phosphonate and a carboxylate; c) a pH buffer; and d) at least one metal complexing agent. The composition is preferably maintained at a pH of between about 4.5 and about 7.5. The near-neutral pH pickling compositions can be used on a variety of metallic surfaces as well as composite surfaces including metallic and non-metallic moieties. |
