Abstract:

An effective metal finishing technology for obtaining phosphate coatings on A3 carbon steel by ultrasonic at room temperature was described.The phosphate electrolyte did not contain any poisonous and contaminative additives or accelerant.The effects of ultrasonic,phosphating parameters such as temperature,time and pH value on appearance,weight and corrosion resistance of the obtained phosphate coating were studied.

Key words: phosphating,  , ultrasonic,  , room , temperature,  , cavitation,  , corrosion , resistance
