Definitions

  • a method according to the invention is provided for the treatment of an object, a layer of a treatment material being formed on a surface of the object by means of a thermal spraying process, an active ingredient being co-injected with the treatment material.
  • the active substance can accordingly be provided in all layers or only in predetermined layers of the treatment layer.
  • the use of the active ingredient in individual selected locations is preferred, where the active ingredient itself is expensive (e.g. platinum) and its effect should only have an effect on a certain area (e.g. on a free-standing surface).
  • the mouth portion of the gun 24 includes a tube 38 with an open end that faces the workpiece 18.
  • An electrode 40 is provided in the tube 38, and an arc (plasma) 42 is generated in operation, which extends to the workpiece 18 and forms a transport path in the direction of the workpiece 18.
  • the powder particles 44 emerging from the injector 28 (and / or 26) are introduced into this sheet 42 and immediately entrained in the direction of the workpiece 18 and flung against the currently opposing surface part 46 of the workpiece 18.
  • the temperature of the plasma is so high that the powder particles 44 partially melt before they reach the surface of the workpiece 18. Once there, however, they are pressed flat onto the surface part 46, giving off their heat to the workpiece 18 and solidifying immediately. This connects them to the material they encounter.
  • a thin layer (also called “lamella", not shown) is thus initially formed and, by repeating the layer formation, a layer 50 (FIG. 3) of the sprayed material on the surface of the workpiece 18.
  • the thickness of the lamella depends, inter alia, on the on the powder feed speed and quantity and on the linear speed of the gun 24 in the axial direction of the workpiece 18. If each layer is formed the same, the thickness of layer 50 will depend on the number of repetitions of layer formation. Further details of the spraying technique can be found in the above-mentioned paper from Plasmatechnik AG or in the general literature.
  • the simultaneous delivery of both the substrate material and the active ingredient can take place in that the reservoir 34 (FIG. 1) is filled with the substrate powder and the reservoir 36 with the active ingredient powder and the transport gas is fed to both reservoirs 34, 36.
  • the amount of the active ingredient is only a fraction of the amount of the substrate material.
  • a powder mixture with the predetermined proportions of the two components can be prepared and filled into a memory 34 or 36.
  • the transport gas supply can be switched on or off at the appropriate point in time in the appropriate store, another spray powder being able to be provided in the other store.
  • the workpiece 18 is the godet (ie the thread-carrying part) of a draw roll unit for use in the spinning of continuous filaments made of synthetic polymers. Designs of such units are shown, for example in EP-A-454618 and in our Swiss patent application No. 925/94 of March 28, 1994 (PCT / CH94 / 00104).
  • the godet itself is made of steel and its outer cylindrical surface (over which the filaments run during operation) is prepared for receiving a protective layer 50 (FIG. 3) according to the known measures of spray technology. 1, a layer 50 with Al 2 O 3 as a substrate with a total thickness of, for example, 150 ⁇ m is built up.
