A new time–frequency detection method of stray current field interference on metal structures

Investigation on corrosion rate and a novel corrosion criterion for gas pipelines affected by dynamic stray current

“…This requires 24 h probe current monitoring and in spite of its accuracy, it may be very time consuming and difficult to carry out in vast field investigations. Different researchers have proposed other stray current interference and related corrosion criteria based upon potential measurements on both pipeline and railway that have been described elsewhere (Freiman, 2003a(Freiman, , 2003bDarowicki and Zakowski, 2004). It should be noticed that the proposed criteria are just a probability measure for corrosion or overprotection.…”

Studies on pitting corrosion in austenitic stainless steel interfered by square‐wave alternating voltage with different parameters using multi‐potential steps method

“…The lower amplitudes of cathodic branch fail to remove the oxide film on the stainless steel so as to weaken the anodic polarization of the next AV cycle. Darowicki and Zakowski and Mantell proposed that the AC corrosion is closely related to the cathodic process. This part has been examined in section 3.3 by adjusting the duty ratio of anodic to cathodic branches.…”

Stray current‐induced corrosion in cathodic protection installations of steel‐reinforced concrete structures: FEM study of the critical parameters

“…Stray current corrosion induced by electrochemical rehabilitation measures is another topic that is more honoured in the breach than in the observance. Although several papers [ 2–9 ] and even standards [ 10 ] are available concerning the general topic of stray current corrosion induced by DC systems, the DC source is normally not a part of the concrete structure. Thus, the highly conductive current path through the reinforcement is surrounded by low conductive concrete, which has, in this case, shielding properties.…”
