(3) pending band steel is linked to each other with the anode of direct supply, stainless steel substrates links to each other with negative electrode;
(4) passing to pulse current density is 10-25A/dm
2, crest voltage is the pulse direct current of 330-500V, and the burst length is 0.1-5.0ms, equals the burst length interpulse period, and its overall treatment time is 10-60 minute.
According to another embodiment of the invention, comprise that further electrolytic solution contains the trisodium phosphate of 10-35g/L.
According to another embodiment of the invention, comprise that further belt steel surface imposes the pre-plated film of polymer earlier, to increase the initial disruptive voltage of reaction.
