Would sputtering work? What have you tried? How thick do you need the coating?

thanks I think that is what I will do ... how much that will cost?
for the thick coating we don't need a very large one

sorry for my english

Depends where you do it? University will most likely be cheapest, unless you want bulk fabrication.

At my University it cost about $100/hr for lab use (with a max charge of only 4hrs), about$80 for a gram of gold and you'd have to be trained on the evaporator. The only sputter machine in our lab with a free to use gold source leaves low quality gold layer. The best option here at CU is to evaporate, I think in general evaporation leaves a higher quality layer; however, it does cause more thermal stress depending on the apparatus, distance between target and source...
