Abstract

A plating method and apparatus, in which the object (7) to be coated is immersed in a bath (2) in a basin (1). A plating tool (5) is kept permanently in the basin (1), in the vicinity of a pipe or duct (3) passing through the basin, and the object (7) to be coated is not placed in conjunction with the tool (5) until inside the bath (2). In electrolytic plating, a current is supplied to the anodes (5) by means of a conductor rail (4), which is located in the pipe (3) in the basin, which the electrolytic liquid (2) surrounds and which extends above the liquid surface. The object (7) to be coated is immersed in the basin (1) by means of a suspender (8) supported on the upper end of the pipe (3).

Claims (10)

1. A plating method, in which the object (7) to be coated is immersed in a bath (2) in a basin (1), a plating tool (5) is kept permanently in the basin (2) and the object (7) to be coated is not placed in conjunction with the tool (5) until inside the bath (2), characterised in that the plating tool (5) is kept in conjunction with a pipe or duct (3) passed through the basin, and that electric current and/or chemicals are supplied to the plating tool (5) through the said pipe or duct (3).
2. A method as claimed in claim 1 for electrolytic plating, characterised in that the plating tool, which comprises anodes (5), is kept permanently in the basin, that a current is conveyed to the anodes (5) by means of a conductor rail (4) located in the pipe (3) in the basin, which is surrounded by electrolytic liquid (2) and extends above the liquid surface.
3. A method as claimed in claim 1 or 2, characterised in that the object (7) to be coated is immersed in the basin (1) by means of a suspender (8) supported on the upper end of the pipe (3).
4. A plating apparatus, which comprises a plating basin (1) containing a liquid bath (2) and a plating tool (5) immersed in the liquid bath (2), the said tool being permanently in the basin, characterised in that in the basin is a pipe (3) surrounded by the liquid bath (2), in conjunction with which the plating tool (5) is arranged and which comprises means (4) for supplying electricity or chemicals to the plating tool (5).
5. An apparatus as claimed in claim 4 for electrolytic plating, characterised in that the plating tool comprises anodes (5) to which a current is supplied by means of a conductor rail (4) located in the pipe (3) in the basin (1),
6 which the electrolytic liquid (2) surrounds and which extends above the liquid surface.
6. An apparatus as claimed in claim 4 or 5, characterised in that one or more vertical pipes (3) pass through the bottom of the basin (1).
7. An apparatus as claimed in any of the claims 4 to 6, characterised in that the object (7) to be coated can be immersed in the basin (1) by means of a suspender (8) supported on the upper end of the pipe (3).
8. An apparatus as claimed in any of the claims 4 to 6, characterised in that the anode plates (S) comprised in the plating tools are arranged in a circle surrounding the pipe (3) and the arrangement is used for the internal plating of tubular objects of the processing industry.
9. An apparatus as claimed in any of the claims 4 to 8, characterised in that one or more pipes (3) surrounded by a liquid bath (2) are located symmetrically in the basin (1).
10. The use of the method according to any of the claims 1 to 3 or of the apparatus according to any of the claims 4 to 8 for plating objects with a chromium coating.
