Electrochemical noise analysis of cathodically polarised AISI 4140 steel. I. Characterisation of hydrogen evolution on vertical unstressed electrodes

Identification of damage evolution during SCC on 17-4 PH stainless steel by combining electrochemical noise and acoustic emission techniques

“…Several studies performed on stainless steel under various conditions [17] [18] [19] [20] have indicated that it might be possible to measure electrochemical current and voltage noise fluctuations resulting from the periodic activation and propagation of cracks on SCC tests. In some investigations [21] [22] hydrogen embrittlement as a particular kind of SCC and the influence of evolved hydrogen bubbles on the measured EN received special attention.…”

An attempt to detect SCC by combined measurements of electrochemical noise and acoustic emission

“…Some authors 19 have used a similar approach on pre‐cracked coated CT specimens, and found certain oscillations in the measured current, presumably connected to the periodic propagation of the crack. In a few investigations 20, 21 hydrogen embrittlement as a particular kind of SCC and the influence of evolved hydrogen bubbles on the measured EN received special attention.…”

Electrochemical noise: a review of experimental setup, instrumentation and DC removal

“…Poten tiostatic/Galvanostatic mode is usually applied in lab studies, such as SCC monitoring and gas evolution [3,[36][37][38]. In this case, we can only obtain ECN under potentiostatic control or EPN under galvano static control, but we cannot get both of them.…”

“…EN is used in the corrosion engineering field in the beginning and now extends to many other fields like electrodepo sition [1,2], gas evolving electrode [3][4][5], and fuel cells operation [6], as shown in Fig. 1.…”
