Zinc Electroplating Final Year Project

What chemical should I use for zinc electroplating? it is my final year project. I have found several journals on it. it got so many ways on electroplating and different chemical solutions are needed for it.

If I need to apply a coating a layer of zinc alloy on mild steel by using electroplating, what types of alloy should I use besides Zn/Ni and Zn/Co ?

Either acid zinc or alkaline non cyanide are possibilities, William; I would suggest steering clear of cyanide processes. Acid zinc is probably marginally easier. You can apply straight zinc rather than an alloy, but as for alloys, in addition to the two that you mentioned you might consider Zinc-Iron and Tin/-Zinc. Depending on your grade level I believe that you should have a science teacher or faculty advisor helping you with this.

Dear sir ,
I am working in electroplating plant.
my project is phosphating in phosphate panel
I am trying to use as raw material
1 ---- manganese carbonate
2-- nitric acid
3 phosphoric acid
all materials are mixed in dm water
then I am plating for this mixture but no result of phosphate plating so please guide and practical example.

Hi, Ravindra. It is quite unusual for an end user to try to formulate their own phosphatizing process. An experienced phosphatizer could probably do so with some trial and error because they would perhaps know what parameter to adjust if the result was too thin or thick, too dark or light, too crystalline or too amorphous.

Unfortunately, what you are trying to do is similar to a person who hasn't taken a driving lesson and wants not only to be told how to drive but how to build a car at the same time. You really should do one at a time. Learn how to phosphatize with the assistance of the process supplier, and then try to formulate your own if you are still interested.

The information you are seeking is too broad and deep to be practical to deliver in a forum like this, but if you would like background information on phosphatizing, two good books are Samuel Spring's Preparation of Metal for Painting [affil link on Amazon ] and Rausch & Rausch's Phosphating of Metals [affil link on Amazon, ... on AbeBooks -->]. Good luck!
