چکیده
The effect of ammonium thiocyanate (NH4SCN) on the behavior hydrogen entry into low alloy steel under cathode charging was investigated using electrochemical permeation technique. In this study, sides were polarized galvanostatically to control rate evolution reaction. potential, current density and measured at pH 3.0 in acetic buffer solution with without 3 g·L?1 NH4SCN. From Tafel slope reaction dependence concentration density, it confirmed that proceeds Volmer-Tafel mechanism study. NH4SCN drastically increased steel. To analyze results efficiency calculated from relationship among overpotential. It found higher environment than free environment. However, coverage adsorbed atoms side decreased discuss increases efficiency, activation energies adsorption absorption estimated by temperature density. is suggested energy although absorption.

The current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. For this purpose, some experiments including hardness test, non-destructive test (NDT), metallography, and fractograpghy are conducted. The microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (SEM). The microstructural studies show that t...
متن کاملffects of electrochemical reaction and self - stress on hydrogen diffusion in tubular membranes during galvanostatic charging *
Based on theories of hydrogen electrode reactions at the palladium surface and self-stresses of hydrogen in thin tubular shells established earlier, we numerically calculate transport properties of hydrogen across a tubular membrane under galvanostatic charging conditions. It is found that the exited hydrogen flux is much less than the charging current since the hydrogen combination reaction ta...
