Abstract Effects of the square wave pulsed current(SWPC) par ameters i.e. frequency (f),magnitude(IA) and duty cycle(P) on the cathodic polarization potentials(E) and polarization extents(ΔE) of the Q235 steel electrodes were studied in 3%NaCl,0.06%NaCl and tap water.The result s show that E and ΔE change negatively with the increase of IA, f and P,but if E is close or more negative than -1.00V(SCE),the change of E and ΔE will decrease largely.The effects of each current parame ters on ΔE are different and relate closely to E.The general principle and method to adjust the current parameters are indicated that on the basis of a chieving an expected protection status,the SWPCs with lower P and IA a re recommended,and if the current parameters need to be adjusted,firstly frequen cy is adjusted and then IA.

Key words: current square wave pulsed current cathodic protection mechanism
