Immersion Copper Plating on Steel

I'm an Engineering Faculty student of the University of Rome "La Sapienza". I'm studying the possibility to make immersion copper coating on steel. I would like to know some information or solutions composition. I'm using a H₂O solution 10g/l H₂SO₄, 10 g/l CuSO₄.5H₂O, at room temperature for 60-120 s, but the coatings are poor adherent. I look forward to your kind answer

kind regards

First you should heat wires to 60 centigrade - acid pickling - rinse - copper sulphate ⇦ this on eBay or Amazon [affil links] 90 grams /l and H2SO4 35 g/l and EDTA 5 g/l - rinse - benzotriazole ⇦ this on eBay or Amazon [affil links] solution - dry.
good luck.
