“…Crack propagation could be explained by localized metal dissolution along Cr-depleted grain boundaries (Breimesser et al , 2012). Gomezduran and Macdonald (2006) investigated SCC susceptibility of sensitized 304 SS in a thiosulfate solution, and they claimed that the reduction of thiosulfate to sulfur S 0 led to the reduction of H + to H; H would enhance the dissolution of the Cr-depleted grain boundaries by forming hydroxide (Xia et al , 2016). Figure 8(c) shows four well-developed cracks with length ranging from 150 to 600 μm, as marked by letters a and b.…”

Purpose This paper aims to investigate the stress corrosion cracking (SCC) process of sensitized 304 stainless steel during the slow strain rate test by using the electrochemical noise (EN) technique. Design/methodology/approach EN data are interpreted based on chaos and wavelet analyses, and correlation dimension and wavelet energy distribution are used as indicators for SCC process identification. Findings Experimental results reveal that the corrosion potential abruptly decreases from 180 to 100 mV at 6,300 s and the current increases from 10 to 100 nA accordingly, which is attributed to passive film breakdown and crack initiation. Chaos and wavelet analyses results reveal that, as crack initiates, the correlation dimensions increase from 1.2 to 1.9, and the corresponding distribution frequencies of maximum relative wavelet energy change from high frequency to low frequency. Originality/value SCC is monitored in lab, and crack initiation and propagation are identified by chaos and wavelet analyses. This work lays the foundation for SCC detection in field using EN.

“…Table 1 represents the summary of some main published reports on alkyl chain CIs. At present, the alkyl chain CIs are mostly zwitterionic compounds, ionic liquids (IL), surfactants, or modified from surfactants, such as Gemini surfactants [17,18]. Gemini surfactants contain at least two hydrophilic groups (ionic or polar groups) and two hydrophobic chains, so they possess good water solubility.…”

Metal materials are vulnerable to corrosion in the process of production and service, which often leads to serious disasters, including the decline of the performance of metal components and the shortened service life, and even causes catastrophic accidents and ecological damage. Adding a certain amount of corrosion inhibitors (CIs) to the corrosive medium is a simple, efficient, and economical anti-corrosion method to slow down and restrain the corrosion of metal materials. Organic corrosion inhibitors (OCIs) are considered to have good application prospects and are widely used for surface anti-corrosion of metal materials, as they generally have advantages such as good metal adsorption, low oxidation resistance, good thermal and chemical stability, and green environmental protection. This paper systematically summarized some major OCIs, including alkyl chains, imidazoles, and pyridines, and their structural characteristics, as well as the action mechanism of OCIs. Moreover, this paper discusses some natural compounds used as environmentally friendly CIs and provides a prospect for the development trend of OCIs.
