how can I coat metal (copper, aluminium,zinc,etc...) with iron.I don not mean coating of iron with metal (copper, aluminium,zinc,etc...) as well known industrial appliction.I tried electrolysis with iron anode and iron sulfate solution although both anode and cathode bubles  there is no coating .should I change solution temperature ?

Hmmm... so you want to electroplate iron onto copper, or other metals do you.  Hmmm ... tricky.  Well, a little googling turns up some patents for nickel-iron alloy plating, so some other people are working on it.  You may want to try a number of reagents for complexing iron atoms, they might get you better adhesion.

For example, a quick google search leads me to this result:

The abstract is free, and it's not a bad starting point.

To say the least.
