Abstract

899,959. Coating with copper. BRITISH OXYGEN CO. Ltd. Jan. 18, 1961 [Jan. 19, 1960], No. 1920/60. Class 82(2). A ferrous rod or wire is coated with copper by immersing the clean rod or wire in an acid solution of copper sulphate which is subjected to ultrasonic oscillations. The rod or wire 11 is passed via feed rolls 12 through a pickling tank 14 containing hydrochloric or sulphuric acid and then into the coating tank 16 containing an acid solution of copper sulphate which is subjected to ultrasonic oscillations by means of barium titanate transducers 18, the preferred frequency range being 12-80 kc/s and the power input 500 watts per foot of immersed rod or wire. The coppering solution contains 10 to 100 grams copper sulphate and 5 to 800 c.cs. sulphuric acid to 2 litres of water and after coating, the rod or wire is washed by passing through water in tank 20 and finally drawn through a conventional wire drawing die 22. Alternatively the wire may first be passed through an alkaline degreasing solution such as trichlorethylene prior to immersion in the copper sulphate solution.
