Abstract:
The invention relates to sheet metal or a sheet metal blank provided with a lubricant coating, especially an anti-corrosion oil of the Pre-Lube or Dry Lube variety. The sheet metal or sheet metal blank comprises a layer which is formed by applying a solution containing an organic phosphoric acid ester to the metal surface of the sheet metal. Sheet metal provided with said coating has excellent tribological properties.
