摘要: Abstract The effect of different type iron-phosphate coatings on corrosion stability and adhesion characteristic top powder polyester coating steel was investigated. Iron-phosphate were deposited in the novel phosphating bath with or without NaNO 2 as an accelerator. evaluated by electrochemical impedance spectroscopy (EIS), pull-off NMP test, while surface morphology phosphate investigated atomic force microscopy (AFM). improved pretreatment based from -free bath.
