“…Porous sulphides can accelerate corrosion due to the formation of galvanocouples, in which sulphides act as an effective cathode. 11,12 A dark-coloured film with a thickness of 20…30 μm is formed on the steel in a solution containing 100 mg/dm 3 H 2 S for 720 h (Figure 8(a)).

“…[3][4][5][6][7][8][9] The stability of steels in hydrogen sulphide water environments significantly depends on the formation of sulphide films on the surface and their influence on the corrosion rate. [8][9][10][11][12] These films can slow down corrosion processes by creating a diffusion barrier for reactants. The formation and protective properties of the films depend on the chemical composition and pH of the corrosive environment, hydrogen sulphide concentration, temperature, etc.…”

The effect of hydrogen sulphide concentration on the corrosion behaviour of 07Cr16Ni6 austenitic-martensitic stainless steel in a 5% NaCl + 0.5% CH3COOH solution was studied to determine the role of H2S in the corrosion product formation and corrosion mechanism. Unstable passivation of steel is detected in a solution containing <100 mg/dm3 H2S. Steel corrodes in an electrochemically active state at >100 mg/dm3 H2S. When the pitting potential is reached, pitting damage occurs at the grain boundaries. The corrosion rate decreases by ∼five times after exposition for 720 h due to the formation of nickel and iron sulphides on the surface. Corrosion is accompanied by the absorption of 4.2–17.5 ppm hydrogen, 62…70% of which is diffusible and can cause hydrogen embrittlement. The scheme of steel corrosion under the influence of different concentrations of hydrogen sulphide is proposed.

“…This behaviour can be caused by numerous factors. It could possibly be attributed to the formation of a corrosion product film (Figure 6) on the charging surface of the sample, which can interfere with the hydrogen uptake and influence the permeation flux [6,7,18]. This corrosion product was identified by X-ray diffraction as iron sulphide (mackinawite and pyrrhotite).…”

The influence of temper temperature on the environment assisted cracking of seamless 9% Ni steel tubes were investigated using scanning electron microscope (SEM), electron backscatter diffraction (EBSD), X-ray diffraction (XRD), slow strain rate tensile (SSRT) tests, hydrogen permeation tests and electrochemical measurements. Mechanical and electrochemical tests were conducted in sodium thiosulphate (Na 2 S 2 O 3 10 −3 mol L −1 ) solution at open circuit potential (OCP) and at cathodic potential. Results showed that 9% Ni steel had a higher ductility loss at OCP when compared with the results obtained under cathodic potential. The lower ductility loss at cathodic potential was attributed to the inhibition of the anodic dissolution. After the tests, the specimens were examined using scanning electron microscopy to characterise the fracture morphology. The fracture surface exhibited mixed morphology, with a ductile morphology in the centre and a brittle morphology near the edges.

The corrosion behavior of low‐alloy steel exposed to saturated H2S solution is systematically studied using electron backscattered diffraction, scanning electron microscopy, X‐ray diffraction, X‐ray photoelectron spectroscopy, and electron probe microanalysis. The experimental results suggest that the corrosion rate decreases with prolonged immersion time because more corrosion products are formed on the steel surface. The corrosion products consist of mackinawite, greigite, and molybdenite regardless of the corrosion time. The structure of the corrosion products transforms from a single layer into two layers with increasing corrosion time. The Cr content in the corrosion products is similar to that in the steel substrate. The corrosion products are rich in molybdenum owing to the formation of molybdenite.
