Abstract
The present invention relates to a method for producing a chemical conversion layer on a metal surface, comprising the following method steps: (i) providing at least one cloth having a defined area, which is resistant at least in the pH range from 2 to 7 and is tear-proof in the wet state, (ii) bringing the cloth into contact with a liquid, which contains at least one active component for the formation of the chemical conversion layer, so that the cloth is impregnated with the liquid, (iii), applying the cloth impregnated with the liquid to a metal surface, and (iv) removing the cloth from the metal surface at a moment at which the cloth is still at least damp.
Claims18
A method for producing a chemical conversion layer on a metal surface, comprising:
- (i) providing at least one cloth having a defined surface, which is resistant at least in the pH range of 2 to 7 and is tear-proof in the wet state,
- (ii) bringing the cloth into contact with a liquid, which contains at least one active component for the formation of the chemical conversion layer, so that the cloth is impregnated with the liquid,
- (iii) applying the cloth impregnated with the liquid to a metal surface, and
- (iv) removing the damp cloth from the metal surface.
A cloth for the formation of a chemical conversion layer, wherein the cloth is resistant in the pH range from 2 to 7 and is tear-proof in the wet state and has an adsorbed liquid, which contains an active component for the formation of a conversion layer.
A method for producing a chemical conversion layer on a metal surface, comprising:
- (i) providing at least one applicator, which is resistant at least in the pH range of 2 to 7,
- (ii) bringing the applicator into contact with a liquid which contains at least one active component for the formation of the chemical conversion layer, so that the applicator further comprises the liquid,
- (iii) applying the applicator and the liquid to a metal surface, and
- (iv) removing the applicator from the metal surface.
