Summary for copper electroplating onto steel Discussion
Copper electroplating onto steel is the topic of this short thread, where Zia Ullah K. asks what conditions are needed to plate copper on steel and what thiourea does in copper plating. The excerpt shown does not include a technical reply, so no specific process steps, bath chemistry, or pretreatment sequence are provided in the visible text. The only named response context is a site note from Ted Mooney, P.E., but it does not answer the plating question. Because the thread excerpt is incomplete, the safest takeaway is that the question concerns the basic requirements for copper-on-steel plating and the role of thiourea as an additive, but the source provided here does not supply the actual solution.

Hi, Zia.
If you just want to deposit some copper as a science project, please see our FAQ, “How Electroplating Works”.
Functional copper plating on steel is something else, though, because copper will ‘immersion deposit’ onto steel with unsatisfactory adhesion for real-world use. The safest, surest, simplest route is probably to do nickel plating on the steel first.
Thiourea is an addition agent used to refine the grain size and stress, but it has no place is school projects due to its toxicity.
We have hundreds of threads about nickel and copper plating here, but it is difficult to learn by bouncing around. It might be better to try to find a copy of the Metal Finishing Guidebook, because books are more organized and appropriate for tutorial learning than web surfing. Good luck.

Ted Mooney, P.E.
