A. Hi, Manjunatha.
Most of the major suppliers offer zinc-nickel plating processes, and I'm sure there are several right in Bangalore. Your first decision is whether to use an alkaline or acid based zinc-nickel plating process. You should probably talk to at least one supplier of each so you get a balanced perspective on the advantages of each.
They will also recommend a pretreatment cycle, but it will probably be the same as for zinc plating: non-etch clean, etch, desmut, zincate, strip the zincate, re-zincate. The zincated parts can probably go directly to an alkaline plating process, but probably need an alkaline strike before going to an acid plating process.
