“…Tafel curves of EPPAE/SS was shown in Figure 6(a), from which the corrosion potential (E corr ) and corrosion current density (I corr ) were obtained using the Tafel extrapolation method. 41,42 For the bare SS sample, the calculated E corr and I corr are 20.610 V and 6.085 lA/cm 2 , respeactively. After the SS substrates coated with EPPAE (1 lm, 3 lm, 5 lm and 10 lm), a significantly positively shifted E corr of 20.495 V, 20.430 V, 20.305 V and 20.284 V was observed.…”

We describe the synthesis of a novel electroactive photo‐crosslinkable poly(aryl ether), containing tetraaniline pendants and allyl groups (EPPAE). The polymer structure and spectral properties are studied in detail. By introducing the electroactive tetraaniline pandents, EPPAE reveals reversible electrochemical activity, expected electrochromic behavior and good anticorrosive performance. After crosslinking the allyl groups with UV exposure, the resultant polymer (c‐EPPAE) shows drastic change in electrochemical properties. The c‐EPPAE/ITO electrode exhibits declining electroactivity but excellent electrochemical stability, which are associated with densification of the electroactive layer. Furthermore, in the corrosive protection measurements, c‐EPPAE reveals an outstanding protection efficiency (99.92%) for stainless steel substrates. A comprehensive study of electrochromic properties and corrosive protection of EPPAE before and after UV exposure will provide an insightful tool for the developing electrochromic smart windows, electrochromic displays, and anticorrosive paint. © 2016 Wiley Periodicals, Inc.

“…Finally, a third or diffusion layer is made of free ions that move in the remaining electrolyte under the influence of electric attraction and thermal motion rather than being firmly anchored. This model describes the reaction of the metal surface in H 2 O and, importantly, the electrical potential here can be influenced by numerous factors especially the presence of any excess electrons which might accelerate the interfacial reaction (Wendler-Kalsch & Gräfen, 1998;Perez, 2004;Bagotsky, 2006;Hamann & Vielstich, 1997). Measuring these potentials and their changes is important in establishing reproducible and interpretable measurements and is key to electrochemical studies.…”

The capability to perform liquid in situ transmission electron microscopy (TEM) experiments provides an unprecedented opportunity to examine the real-time processes of physical and chemical/ electrochemical reactions during the interaction between metal surfaces and liquid environments. This work describes the requisite steps to make the technique fully analytical, from sample preparation, through modifications of the electrodes, characterization of electrolytes, and finally to electrochemical corrosion experiments comparing in situ TEM to conventional bulk cell and microcell configurations.

Abstract. According to the complex process and lots of equipment, there are risks in gas compressor station. At present, research on integrity management of gas compressor station is insufficient. In this paper, the basic principle of Risk Based Inspection (RBI) and the RBI methodology are studied; the process of RBI in the gas compressor station is developed. The corrosion loop and logistics loop of the gas compressor station are determined through the study of corrosion mechanism and process of the gas compressor station. The probability of failure is calculated by using the modified coefficient, and the consequence of failure is calculated by the quantitative method. In particular, we addressed the application of a RBI methodology in a gas compressor station. The risk ranking is helpful to find the best preventive plan for inspection in the case study. Keywords. RBI; Risk Analysis; Gas compressor station; IntroductionThe gas compressor station is the pressurizing part of the pipeline, once the explosion damage is great, and the shock waves generated great, huge shock waves also endanger the people and things surrounding. The integrity management in the gas compressor station is to identify and evaluate the risk of the gas compressor station by using scientific methods. It is a kind of advanced risk prevention and risk management method. Effective measures are taken to eliminate or reduce the impact of risk so that the risk can be controlled in the acceptable range. Finally, accidents are reduced to guarantee safety operation of the gas compressor station in an economic and reasonable way. RBI is an effective way to solve pressure vessel and pipeline integrity problems in the gas compressor station. By Risk analysis of pressure vessels or pipes, the failure mechanism and testing technology of the pressure vessel or pipeline can be determined. Further, inspection plan and spare parts plan can be optimized. Besides, the scientific decision can be provided to support for prolonging the service life and shortening the maintenance period [1]. The RBI technology originated in the nuclear power industry, in the 1970s. In 1985, the American society of mechanical engineering (ASME) set up a research group of risk analysis. From 1991 to 1999, the ASME have published the RBI guidance documents in different industries [2]. Because of the Det norske veritas (DNV) has the ability in risk management and the experience in performing integrity around the world for a long time [3], American Petroleum Institute (API) seeks cooperation with DNV in the Early 1990s. They have successfully transplanted the RBI technology to the integrity management of petrochemical equipment, and have promulgated the RBI technology in the field of two landmark
