For friction surfacing three different set of parameters were applied to get the minimum thickness. Hence it does not cause weight increases in coated substances. On mild steel plate both stainless steel 304 and stainless steel 316 has given a proper coating. But with copper as a mechatrode it forms flash rather than coating. Because of easy deformation of metal when copper rod is used, the coating will not form.
For electro plating, with time of contact of work piece in electrolytic bath as a parameter minimum thickness obtained. Onmild steel plate coating successfully obtained by copper, zinc and nickel but not with stainless steel. Since pure metal only gives coating in electro plating
