investigation of the rotation speed on corrosion behavior of hp 13cr stainless steel in the extremely aggressive oilfield environment by using the rotating cage test
Corrosion Science, 2018Co-Authors: Guanxin Zeng, Dake Xu, Xuanpeng Li, Cheng Zhang, Yang Zhao, Fuhui WangAbstract:Abstract The influence of rotation speed on the scale film and pitting mechanism of HP-13Cr SS in high temperature (>180 °C), high salinity (Cl− concentration >60,000 mg/L) and high CO2 pressure (>4 MPa) oilfield environment was investigated using surface analysis and electrochemical techniques. The results delineated rotation speed decreased the mechanical properties and volume fraction of the amorphous Cr(OH)3(s) of the scale film. As a result, rotation speed increased the both nucleation susceptibility and Growth Probability of pitting, the serious pitting corrosion occurred and the geometry changed to shallow-disk shape.

electrochemical noise analysis on the crevice corrosion behavior of ni cr mo v high strength steel using recurrence plots
Journal of Applied Electrochemistry, 2011Co-Authors: Yawei Shao, Guozhe Meng, Fuhui Wang, Tao Zhang, Yuan CongAbstract:This article makes a study of electrochemical noise analysis on the crevice corrosion behavior of Ni–Cr–Mo–V high strength steel using recurrence plots. The crevice corrosion behavior of Ni–Cr–Mo–V high strength steel was investigated by the electrochemical noise (EN) technique and SEM observation. The experimental results reveal that the crevice corrosion could be distinguished by three stages including induction stage, transformation stage, and stable stage. While increasing the Growth Probability of metastable corrosion, the presence of crevice decreases the initiation rate of metastable corrosion. In the case of crevice, the metastable corrosion is easy to develop into stable one.

effect of hydrostatic pressure on the corrosion behaviour of ni cr mo v high strength steel
Corrosion Science, 2010Co-Authors: Yange Yang, Yawei Shao, Guozhe Meng, Fuhui Wang, Tao ZhangAbstract:Effect of hydrostatic pressure on the corrosion behaviour of Ni-Cr-Mo-V high strength steel was investigated by electrochemical measurements and SEM observation. The electrochemical noise (EN) data was analyzed based on non-linear dynamic theory. The experimental results revealed that hydrostatic pressure decreased the corrosion resistance of Ni-Cr-Mo-V steel and the corrosion at high hydrostatic pressure was more uniform due to the higher initiation rate and lower Growth Probability of metastable pitting.

electrochemical noise analysis on the pit corrosion susceptibility of mg 10gd 2y 0 5zr az91d alloy and pure magnesium using stochastic model
Corrosion Science, 2008Co-Authors: Xiaolan Liu, Yawei Shao, Guozhe MengAbstract:Pit corrosion susceptibilities of Mg-10Gd-2Y-0.5Zr alloy, AZ91D alloy and pure magnesium were investigated by means of electrochemical noise (EN). The EN data have been analyzed based upon the combined stochastic theory and shot-noise theory. Pit initiation process has been modeled as a nonhomogeneous Poisson process and analyzed using a Weibull distribution function. Pit Growth process has been simulated by a nonhomogeneous Markov process and analyzed using Gumbel distribution function. The EN results implied that Mg-10Gd-2Y-0.5Zr alloy had the highest pit initiation rate and pit Growth Probability, which revealed that Mg-10Gd-2Y-0.5zr alloy had the highest pit susceptibility.

acquisition announcements and stock market valuations of acquiring firms rivals a test of the Growth Probability hypothesis in china
Strategic Management Journal, 2013Co-Authors: Ajai S Gaur, Shavin Malhotra, Pengcheng ZhuAbstract:To examine the impact of acquisition announcements on the stock market returns of rivals of the acquiring firms, we propose a Growth Probability hypothesis: when an acquisition is announced, it signals the potential for future Growth in the acquirer's industry to the market, resulting in positive stock market reactions to rivals of the acquiring firms. We test the Growth Probability hypothesis with a longitudinal sample of Chinese domestic and cross-border acquisitions during 1993–2008. The results provide robust support for this hypothesis as a means to explain market reactions to rivals of acquiring firms. We also empirically test and negate alternative theoretical explanations advanced in prior literature to explain positive market reactions to rivals of the target firms.
