Mr. Hashemadeh, we applaud your curiosity, but the multitude of questions you ask are answered by entire libraries of books, and a reply to your posting could never take the place of those libraries. The closest thing you will find in one volume is probably the Metal Finishing Guidebook, which does come with that subscription to Metal Finishing magazine that you expressed interest in.
