Hello, Mr. Bayat. I would suggest that you study the metal finishing journal literature of about 20 years ago, and expired patents, of which there are hundreds on this subject. There are also excellent books on this subject.

There is nothing wrong with seeking such information so that you can manufacture and distribute your own phosphatizing chemicals, but successful formulations are actually rather complex, and printing detailed formulation information on this forum from semi-anonymous people could mean inadvertent dissemination of trade secret info. Sorry, but we can't print detailed formulation info -- although we would be very happy to reference any published info that anyone provides.

Like always Ted is right. But very simple and not so bad processes exists. Just immerse your objects (iron or low alloyed steel) in solution of 15 gm phosphoric acid/20 gm tannic acid on eBay or Amazon [affil link] /1 lit water (tannic acid on eBay or Amazon [affil link] can be omitted). After that, dry it without rinsing and then you must lacquer or wax it.

Good luck!

Letter 31345 is something for you Mohammad. Good luck!
