HI
I have a copper strip and this strip is used as a contact for carrying high current. Due to high current, arcing is taking place whenever the strip establish the contact. On the other hand I have the limitation to maintain the copper density, where I could not able to increase the size or wall thickness of the copper.
Due to this arcing and size limitation, my copper strip erode, in order to reduce the copper erosion due to arcing, Ive planned for Graphene coating on the same.
If I can do Graphene coating, what are the parameters I should take care and how should i do the coating?
I appreciate one and all for the reply, kindly please share your experience, idea or thought
Growing graphene on copper foil is one of the most common way to grow large area graphene. You can try to grow graphene on your copper strip if you have a CVD system. This is the first paper that demonstrate this method and there are plenty followup works which you can look them up.

CVD is a common way but you can use the hot plate and spray graphene or drop it after heated the copper foil ( after dispersed graphene in hydrocarbon solution )

If i have a graphene powder and I heat my copper strip, How shall I apply the powder. If the graphene is as a homogeneous solution, the dispersion of graphene on the copper would be uniform and homogeneous.
Is there any other method where I can coat the graphene

I do not have a facility of CVD for graphene. If you can give me few inputs where I can use readily available graphene for coating
The other way maybe reduced graphemes oxide. I believe you can buy graphene oxide from vendors and disperse them in solutions. Then, either spray or put your copper in the solution and take it out. Heat it up to reduce graphene oxide and make it rGO. You might have to tune the solution and some other parameters to get good coverage.
