Help in blackening formulations

I want technical help to formulate blackening chemicals and electroplating chemicals for zinc and nickel and also goldening coaters.

You will need to hire a consultant with experience in this, Mr. Grewal; even then, you're asking a lot. The major plating chemical suppliers have invested hundreds of man-years in their process development, and there is obiously no way you can obtain equivalent knowledge in short order. A good place to start, though, is the old plating journals of 40 to 50 years ago, where you will find early knowledge on the topics.
