Abstract: A new water soluble acrylic anodic electrophoretic coating was prepared. The influences of 45^# steel's phosphate coating and electrophoretic technology parameters on the performances of coatings film were studied. The results showed that the transparent film was featured by its good quality and smooth & lustrous appearance. Phosphate coating can enhance the adhesion, thickness and hardness of coatings film. The best mild-phosphating time was 6 min. The optimum electrophoretic technology parameters were voltage 30 V, 25℃,90 s and a distance of 4 cm between cathode and anode.
