Effects of thiosulfate on stress corrosion cracking (SCC) susceptibility (S) of type 316 (UNS S31600) stainless steel (SS) were studied. Addition of sodium thiosulfate (Na2S2O3) to 3.5% sodium chloride (NaCl) increased S of type 316 SS to SCC. A quan

Effects of chloride ions (Cl−) on hydrogen absorption into iron and on the hydrogen evolution reaction (HER) on an iron surface were studied in acid and alkaline solutions at 23°C using th...

The results presented show that benzotriazole (BTA) inhibits the absorption of hydrogen into iron which is cathodically polarized in an acid (pH {approx_equal} 1.7) sulfate solution. Analysis of the results indicates that BTA inhibits also the hydrog

A mathematical model is developed to simulate the electrowinning of non-noble metals (e.g., Zn, Cr) within flowthrough porous electrodes under the conditions of simultaneous evolution of hydrogen gas bubbles. The results of the model are presented as

The electrochemical behaviour of a low-aluminium copper alloy (Alfa aluminium-bronze) in concentrated (1–8 N) NaOH is characteristically passive over broad potential regions, exhibiting passive currents that increase with alkali concentration. This

This article presents a mathematical model of the selective dissolution process that occurs below a critical potential, EC, in a thin alloy surface layer which becomes protective as it enriches in the noble metal. A kinetictransport product h (cm−1

The corrosion behavior of a low alloy steel (Fe-2.25 Cr-1 Mo) was investigated in 1 m NaCl over a range of high temperatures with various levels of contamination with CuCl2. The net weight loss of the alloy and the weight of the corrosion product fil

An autocatalytic mechanism is shown to explain the kinetics of the surface reaction occurring during the low-temperature reduction of sintered hematite pellets with hydrogen between 300 and 500°C. The results satisfactorily fit the predictions of a

The aim of this work was to test the feasibility of using commercially available Cu screens as cathodes for the electrolytic production of hydrogen. The screens were stacked in the form of packed bed flow-through electrodes. The effects of the variou

This paper presents an interpretation of the experimental results obtained on the electrowinning of zinc at a flowthrough porous electrode in light of a mathematical model which was presented in Part I. The process is accompanied by simultaneous hydr
