Definitions
- the invention relates to a method for currentless Deposition of copper coatings on iron and Iron alloy surfaces using solutions that Contain copper and hydrogen ions, as well as a solid one Concentrate for performing the procedure.
- US-A-3,460,953 teaches a process for the electrodeposition of brass-like Coatings on steel with an aqueous solution, which in addition to copper, nickel, Tin and sulfate also sodium chloride, sulfuric acid, boric acid and / or Citric acid and optionally glutaric acid, succinic acid, glycolic acid, Diglycolic acid, its derivatives or / and other additives.
- the object of the invention is to provide a method for Electroless deposition of copper coatings on iron and To provide iron alloy surfaces that the does not have known, in particular the aforementioned disadvantages and is able to produce even and adherent coatings.
- the object is achieved with a method for the electroless deposition of uniform, adhesive and possibly highly shiny copper coatings for cold working on iron or iron alloy surfaces with the aid of solutions containing copper and hydrogen ions, which is characterized in that the surfaces with a aqueous solution that essentially comes out in contact 5 to 30 g / l Cu essentially based on CuSO 4 , 0.2 to 5 g / l Mg essentially based on MgSO 4 and sulfuric acid as well Polyglycol and / or table salt with the weight ratio of Cu: Mg in the range of (35 to 5): 1.
- a weight ratio of Cu: Mg in the range of (35 to 5): 1 leads to one optimal gloss of the coating produced.
- polyglycol can improve the adhesive strength of the Achieve coating, by the salt of a uniform attack to reach the iron or iron alloy surface.
- Part of the invention is a solid concentrate for preparing and supplementing the solution intended for carrying out the process, which consists of at least 85% by weight of CuSO 4 • 5 H 2 O and MgSO 4 (anhydrous) with a weight ratio of (35 to 5 ): 1 (calculated as Cu: Mg).
- the fixed Concentrate additionally a maximum of 10% by weight of polyglycol and according to a further advantageous embodiment maximum 5% by weight of table salt.
- the Iron or iron alloy surfaces from Contaminants, especially rust and scale, are freed. This is conveniently done by pickling in Mineral acid, preferably by pickling in hydrochloric acid or Sulfuric acid. Then it is rinsed with water.
- the pickling process a cleaning stage upstream.
- Copper coatings have considerable adhesive strength and have a strong sheen. Another advantage the procedure is that the iron rise in the Copper plating solution is slowed down significantly so that - without influencing the iron concentration in the solution is taken - a larger throughput of iron or Iron alloy surface is possible.
- the solid also forming part of the invention Concentrate is characterized by the fact that it itself long storage well pourable and therefore light is manageable.
- the effectiveness of the copper plating solution was increased by adding a solid concentrate which contained 90% by weight CuSO 4 .5H 2 O, 8% by weight MgSO 4 (anhydrous) and 2% by weight polyglycol, and by adding sulfuric acid the above values.
- the steel wires treated by the process had a uniform, adhesive copper coating with a layer weight of 20 g / m 2 .
- the copper plating solution took up 18.5 g of iron per m 2 of penetrated steel surface.
- the amount of iron dissolved was 22 g / m 2 . That is, without measures to reduce the iron content, the approximately 1.2 times the amount of steel wire could be provided with a copper coating without loss of quality when using the method according to the invention.
- the Cu: Mg weight ratio was 30.2: 1 Temperature of the solution was set to 60 ° C Contact time was 30 sec.
- the components of the solution were kept at the above-mentioned values.
- the steel wires had a uniform copper coating with very good adhesion and considerable shine.
- the layer weight was 4 g / m 2 .
- the copper plating solution took up 3.7 g of iron per m 2 of wire surface penetrated.
- the amount of iron dissolved was 4.4 g / m 2 .
- the process according to the invention therefore allowed an approximately 20% higher wire throughput without a deterioration in the quality of the copper coatings obtained.
