A. Hi, Mohammad.

Indeed, each of these subjects fill entire books as James implies. I would especially suggest the Metal Finishing Guidebook or the Electroplating Engineering Handbook. After you've had a quick look at one of these, if you have more specific questions, I'm sure James or I, or one of our other readers, will be able to help you address them! Good luck :-)
