Definitions
- the invention relates to a method for coating the Surface of copper materials with a protective layer, in which the copper material by applying a Top layer alloy is provided with a top layer and then in the area of an order area Protective layer by melting one Protective layer alloy with laser radiation and by an im essentially in the area of the order area Melting of the copper material is connected to it.
- JP-A-62 027 561 is a Melting a layer of a nickel and Cobalt alloy disclosed by means of a laser, the Layer of a nickel and cobalt alloy - that of Protective layer alloy corresponds - through thermal Syringes are applied and previously on the substrate Nickel alloy is applied.
- the nickel or Cobalt layer and the nickel alloy Layer are remelted by a laser beam, however follows clearly from the last sentence of the abstract, that the remelting is a firm connection between the Protective layer and the “plated layer” and a connection between the "plated layer” and the substrate with high Creates adhesion, but this also means that even after remelting using the laser, the "plated layer "is preserved from the nickel alloy and thus still exists.
- the invention is therefore based on the object of a method to provide the surface of copper material with to improve a protective layer such that the protective layer on the one hand sufficient hardness and good adhesion and also covering large areas can be applied.
- the advantage of the method according to the invention is there too see that by providing the copper material with the Cover layer whose optical properties for laser radiation be changed so that on the one hand with the laser radiation melting of the components of the protective layer is possible, and on the other hand also a melting of the Copper material in the area of the application area and thus a intimate connection between the protective layer and the Copper material, especially with a metallurgical composite to the copper material, can be produced.
- the laser beam is melted the top layer and slight melting of the Copper material creates a weld pool, in which then the protective layer alloy forming the protective layer is introduced, the protective layer alloy either is melted directly in the weld pool or before Impact in the weld pool by the laser beam is heated or melted and in the melt pool together with the components of the top layer Protective layer is formed.
- the cover layer is made of does not impair the properties of the protective layer Material is, because in this case an installation of the material of the Cover layer in the protective layer no negative Has an impact on their properties.
- cover layer made for mechanical properties of the protective layer of inert material is.

- top layer and the protective layer are the same components, preferably in the same composition.
- the top layer combines and that to form material supplied to the protective layer easily into one uniform layer now forming the protective layer.
- the cover layer serves to absorb the laser radiation to change the copper material in such a way that this no longer or only in the laser radiation reflected to a small extent.
- the cover layer is sufficient is thin to run simultaneously with the Copper material melted due to the laser radiation become.
- the thickness of the cover layer is approximately, for example 100 to about 300 ⁇ m, while the whole is forming Protective layer on the order of about 1 to about 3 mm, preferably 2 mm.
- the mass of the alloy applied as a covering layer is available to the mass of the protective layer alloy subsequently applied in a ratio of about 1 to 3 to about 1 to 5.

- Such layers can be easily and apply inexpensively and thus represent an advantageous Pretreatment of the copper material used according to the invention represents.
- the method according to the invention is preferably so carried out that adjacent application areas themselves overlap.
- adjacent application areas form a coating track.
- a width of the coating track one dimension of the application area across from it Corresponds to the longitudinal direction of the track.
- the copper material in the area of Application area is melted. It is preferably provided that the copper material in the area of the application area melted over a certain depth as a thin layer becomes. It is preferably provided that the copper material co-melted at least over a depth of 10 to 50 ⁇ m becomes.
- a particularly advantageous anchoring of the protective layer to achieve in the copper material is provided, for example, that the copper material in a portion of the Application area is melted by the deep welding effect.
- the protective layer extends in this Area deep into the copper material and is in this thus positively anchored over a nose.
- the copper material for applying the Protective layer is preheated, preferably to a temperature between about 100 ° C and about 500 ° C, in particular approximately between 200 ° C and approximately 400 ° C.
- the invention relates to a workpiece a copper material provided with a protective layer, which is characterized according to the invention in that the Copper material in the area covered by the protective layer is melted on the surface and that the protective layer from several adjacent coating traces is formed.
- the protective layer in a part of their coverage of the workpiece with anchored positively in the copper material is.
- a workpiece 10 on a surface 12 provided with a cover layer 14 applied thereon is, as shown in Fig. 1, in a first Method step a workpiece 10 on a surface 12 provided with a cover layer 14 applied thereon.
