“…Corrosion in polar environments experienced by steel materials is complex and unique. The three commonly used methods to enhance the corrosion resistance of polar steel materials are alloying, coating technology, and cathodic protection technology [72][73][74][75][76][77][78]. These approaches are used to reduce the corrosion of polar steel materials.…”

The desire to explore the natural resources and geopolitical patterns of the North and South Poles has significantly increased the interest of experts and researchers in the development and utilization of the polar regions. In this article, we comprehensively analyzed the current state of the development of polar low-temperature steel around the world. We highlighted the challenges that must be addressed in the ongoing development efforts and summarized the expected future trends in this field. The main theme of this article involves the challenges encountered in polar environments primarily caused by the low-temperature toughness and seawater corrosion of marine steel.

“…XRF is an instrument that can be used for rapid simultaneous determination of multiple elements. The XRF uses physical principles to detect the elements of a substance and can be used for qualitative and quantitative analysis [15][16][17][18] . That is, X-ray penetrates the internal electrons of atoms, and the outer electrons supplement to produce characteristic X-rays.…”

Oilfield injected water scaling often has a great impact on production and development. In this study, the scaling mechanism of injection well was studied, and the scale samples were analyzed by X-ray diffraction and other methods to determine the elements and mineral composition of scale samples and finally determine the main components of scale samples, providing a basis for subsequent water quality treatment. The results show that scale formation in Yu jia ping oil area is mainly caused by corrosion, inorganic salt scale caused by chemical reaction and sediment carried by injected water. Among them, inorganic salt scale is the main scaling component, and its main reason is the changes of ions in the injected water under different chemical environments. After a series of chemical and physical reactions, some ions in the injected water will form insoluble, insoluble and slightly soluble inorganic salts. After long-term accumulation, it is easy to form scale, namely the so-called inorganic salt scale. Inorganic salt scale is generally composed of sulfate and carbonate, the more typical calcium carbonate, calcium sulfate, barium sulfate, etc.

“…In general, the microstructural characteristics of low-alloy steel can influence its corrosion behavior. [52,74,75] Fine grains exhibit excellent corrosion resistance, while ferrite shows better corrosion resistance than pearlite when steel is exposed to H 2 S solution. Acicular ferrite with a smaller effective grain size also exhibits better corrosion resistance.…”

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.
