Effect of surface damage induced by cavitation erosion on pitting and passive behaviors of 304L stainless steel

Effect of nitrogen content on corrosion behavior of high-nitrogen austenitic stainless steel

“…9a, it can be seen that the steady-state current density value of HNSS1 is 1.11 × 10 −7 A cm −2 , and the steady-state current density value of HNSS2 is 1.52 × 10 −7 A cm −2 . Lu et al 58 found that the lower the current density, the more stable the passive film is. Therefore, the passive film formed on the surface of HNSS2 is more stable and has a higher protective ability on the substrate than HNSS1.…”

Effects of cavitation erosion-induced surface damage on the corrosion behaviour of TA31 Ti alloy

“…According to shot noise analysis of EN data, Hu et al found that metastable pitting and stable pitting could be identified by shot noise parameters q and f n [16] . In previous study, we employed EN technology to evaluate the corrosion behaviour of stainless steel (304L) and Ni-Al bronze (9–4-4–2) in 3.5 wt% NaCl solution after CE over various durations [17] , [18] . However, the corrosion behaviour of Ti alloys, which usually have a stronger passivation capacity, with different CE times remains unclear.…”

Cavitation erosion-corrosion behaviour of Fe-19Cr-15Mn-0.66 N high nitrogen austenitic stainless steel in sodium chloride solution

“…High nitrogen austenite stainless steel (HNSS) has gained widespread usage due to its superior mechanical properties and corrosion resistance [3][4][5]. Cavitation erosion (CE) generally induce severe damage of hydraulic components in flowing and ultrasonic systems [6][7][8]. The CE behaviours of HNNSs have been intensively investigated in the past several decades [9][10][11][12][13][14].…”
