A high-resolution characterisation of localised corrosion of AA5083-H111 in simulated seawater by TEM Corros. Eng. Sci. Technol. (IF 1.8) Pub Date : 2022-12-31 Yuanyuan Ji, Yingchang Mao, Lihua Dang, Da-Hai Xia, Wenbin Hu
ABSTRACT The localised corrosion of aluminium alloy (AA) 5083-H111 in 3.5 wt-% NaCl solution was studied by combing scanning electron microscope (SEM), focused ion beam (FIB) and transmission electron microscopy (TEM) techniques. It was found that the Ti-rich intermetallic particles (IMPs) served as the cathodes and triggered the dissolution of its adjacent Al matrix; as a result, a trench was formed

Application of the random forest algorithm to predict the corrosion losses of carbon steel over the first year of exposure in various regions of the world Corros. Eng. Sci. Technol. (IF 1.8) Pub Date : 2022-12-31 Marina Gavryushina, Andrey Marshakov, Yuliya Panchenko
ABSTRACT The random forest (RF) algorithm was used to develop two models for predicting the first-year corrosion losses (C1) of carbon steel in open air in various regions of the world. The first RF model built using combined databases of international programmes ISO CORRAG, MICAT and ECE/UN and tests conducted in Russia is intended for estimation of C1 in various types of atmospheres in various regions

Smart corrosion inhibitors for controlled release: a review Corros. Eng. Sci. Technol. (IF 1.8) Pub Date : 2022-12-28 Xingxing Zhou, Qiangsheng Dong, Dali Wei, Jing Bai, Feng Xue, Baosen Zhang, Zhixin Ba, Zhangzhong Wang
ABSTRACT Metal corrosion has been one of the most urgent problems bringing about great economic loss and life threats worldwide. Corrosion inhibitors can prevent metal from corrosion when directly added to corrosive media, which is a low-cost and efficient strategy towards corrosion protection. However, the corrosion protection ability cannot be durable without continuous additions of corrosion inhibitors

Corrosion behaviour of Ni-based alloy Inconel 740H in supercritical carbon dioxide at 650–700°C Corros. Eng. Sci. Technol. (IF 1.8) Pub Date : 2022-12-20 Bo Xiao, Naiqiang Zhang, Kaiyang Li, Zhongliang Zhu, Tianyi Zhang, Mi Zhou
ABSTRACT Corrosion tests of Ni-based alloy Inconel 740H were carried out in supercritical carbon dioxide (S-CO2) at 650–700°C under 25 MPa. The corrosion kinetics were measured by weight change as a function of time, and the surface oxide layers were characterised and identified by a series of characterisation methods. It is found that Inconel 740H experienced general oxidation, localised exfoliation

The effect of Mn addition on corrosion behaviour of equiatomic CoCrFeNi high entropy alloys in NaCl solution Corros. Eng. Sci. Technol. (IF 1.8) Pub Date : 2022-12-10 Chenglong Zhang, Min Zhu, Yongfeng Yuan, Shaoyi Guo
ABSTRACT The corrosion behaviour of equiatomic CoCrFeNi and CoCrFeNiMn high entropy alloys manufactured by the vacuum arc melting were studied in 3.5 wt-% NaCl solution. And the reasons for the differences in corrosion resistance were investigated in terms of microstructure, electrochemical behaviour and oxide film. The results show that the two alloys exhibit different corrosion characteristics, with

Evaluation of corrosion behaviour of turmeric-coated AZ51 alloy in simulated body fluid for biomedical applications Corros. Eng. Sci. Technol. (IF 1.8) Pub Date : 2022-12-08 Bhaskarjyoti Das, Muralidhar Yadav, Sukumar Kundu, Tapendu Mandal
ABSTRACT In this study, the corrosion behavior of turmeric-coated AZ51 alloy is studied in a simulated bodily fluid (SBF) and then correlated using different characterization techniques. Optical microstructures of all the samples reveal the presence of grains of the α-Mg alloy and precipitates of β-Mg17Al12. Two well-defined peaks were obtained from the XRD patterns -Mg and Mg17Al12, correlating with
