Tribocorrosion of Passive Materials: A Review on Test Procedures and Standards

Figure 12

Potential and current response measured by electrochemical noise technique on (a) AISI 304 stainless steel and (b) duplex treated 304 against corundum in HBSS. In both cases, the potential decreases and the current increases during sliding, as a consequence of removing the passive layer and exposing the bare material to electrolyte [89].
