Process for treating metal surface |
| abstract |
An improved process for treating metal surface comprising a combination of the non-aqueous phosphating treatment and the non-aqueous chromic acid chemical conversion treatment is disclosed. The process is characterized in that the chromic acid chemical conversion treatment is carried out using a treatment solution in which chlorofluorinated hydrocarbon is used as the solvent and confers the metal surface with excellent adhesion property with regard to coating film or paint. |
