| 摘要 |
The invention relates to a method for coating a metal surface, such as the surface of liquid flow tubes (3) used in cooling radiators and heat exchangers, with a thin layer of material containing metal. In the method, the material (6) intended for coating is caused to adhere to the tube in a container-like space (5), whereupon the liquid flow tube (3) is passed out of the container-like space (5) and the material layer (15) intended to form a coating is adjusted to a predesired position and thickness. According to the method, the elongated side faces (14) of the liquid flow tube (3) are caused to collapse towards each other, whereupon the liquid flow tube (3) is passed into the container-like space (5), where coating material (6) is adhered to the surface of the tube (3). After the adherence, the original profile of the tube (3) is restored by causing the elongated side faces (14) of the tube (3) to buckle outwards from each other.
