Phosphatizing produce an uniform coating on metal surface by corrosion reaction. Therefore, metal surface of electrochemical and metallurgical states prior to phosphatizing is essential.
The explanations and problems of electrochemical and metallurgical states as above for phosphatizing on steel are discussed.
Then, the chemical stability and practical quality for zinc phosphate coatings are fully explained.
