Abstract

Effect of temperature on the corrosion behavior of CoCrNi medium-entropy alloy (MEA) in 3% NH4Cl solution was investigated by means of electrochemical measurements, immersion test and statistics analysis. The results show that increasing temperature makes it more difficult to form stable passive film on the MEA surface, accelerates the rupture of the film and reduces the anti-corrosion resistance of the MEA. Particularly at higher temperature, the corrosion rate of the MEA increases, as well the size and number of pits increase. In addition, NH4+ is further hydrolyzed with increasing solution temperature, which promotes the initiation and propagation of metastable pitting, slows down the re-passivation process and enhances the possibility of transition from metastable pitting to stable pitting.

Abstract

A comparative study on the corrosion behavior of CoCrNi medium-entropy alloy (MEA) with CoCrFeMnNi high-entropy alloy (HEA) in SO2-polluted marine environment was investigated by a series of tests. Results indicate that CoCrNi MEA possesses smaller passive current density, larger polarization resistance and lower corrosion rate compared with those of CoCrFeMnNi HEA, which demonstrates that the MEA possesses better anti-corrosion performance than the HEA. This could be ascribed to the detail difference in the microstructure and passive film of the two alloys. Compared with the MEA, the smaller grain size and the larger number of oxides reduce the anti-corrosion performance of the HEA. Moreover, the oxide and matrix constitute the micro-galvanic corrosion cell, which promotes the generation of pits. [ABSTRACT FROM AUTHOR]

Abstract

The ARGO-YBJ detector, located at the Yangbajing Cosmic Ray Laboratory (4300 m a. s. l., Tibet, China), was a "full coverage" air shower array. The high altitude location and the frequent occurrence of thunderstorms, made ARGO-YBJ suitable to study the effects of atmospheric electric fields (AEF) on secondary cosmic rays. By analyzing the data of the ARGO-YBJ detector recorded during thunderstorms, significant variations of the rate of detected showers have been observed. During 20 thunderstorm episodes in 2012, the variations of the shower rates (both increases and decreases of amplitudes up to a few percent) are found to be correlated to the intensity and polarity of the AEF, and strongly dependent on the primary zenith angle. To understand the observed behavior, Monte Carlo simulations have been performed with CORSIKA and G4argo (a code based on GEANT4). We found that the data are well consistent with simulations, assuming the presence of a uniform electric field in a layer of thickness of 500 m in the atmosphere above the observation level. Due to the AEF accelerates/decelerates and deflects the secondary charged particles (mainly electrons and positrons) according to their charge, modifying the number and position of particles with energy exceeding the detector threshold. For the differences in electron and positron flux, spectrum, and lateral distribution, the AEF has an asymmetric effect on the shower particles, producing significant variations of the particle pattern on the ground, and, consequently, on the rate of detected showers, consistent with observations.
