Special Issue Information

Dear Colleagues,

This Special Issue entitled “Corrosion and Coatings: Advances in Protection and Degradation Studies” is of paramount importance in the field of materials science and corrosion engineering. This subject, which encompasses both the study of coating corrosion and their degradation mechanisms, as well as the development and application of coatings to minimize corrosion, addresses major economic and technological challenges. Indeed, corrosion is a global problem that costs billions of dollars annually to industry and jeopardizes infrastructure safety. In a context where material durability and efficiency are crucial, understanding and mastering corrosion processes and developing innovative protective coatings are essential to extend equipment lifespan, reduce maintenance costs, and improve system reliability across various sectors such as aerospace, automotive, construction, and energy. This theme, which reflects current research interests and expertise in the field, also offers the opportunity to explore a wide range of contributions from different areas of corrosion science and coating technology, thus fostering interdisciplinarity and innovation in this critical area of material research.

This work deals with the effects of a non-electrochemically deposited copper- or nickel–phosphorus-based coating on the resulting resistance of traditional X42 grade pipeline steel against hydrogen embrittlement (HE). The susceptibility to HE was determined by the evaluation of the hydrogen embrittlement index (HEI) from the results of conventional room-temperature tensile tests using cylindrical tensile specimens. Altogether, three individual material systems were studied, namely uncoated steel (X42) and two coated steels, specifically with either a copper-based coating (X42_Cu) or a nickel–phosphorus-based coating (X42_Ni-P). The HEI values were calculated as relative changes in individual mechanical properties corresponding to the non-hydrogenated and electrochemically hydrogen-precharged tensile test conditions. Both applied coatings considerably improved the hydrogen embrittlement resistance of the investigated steel in terms of decreasing the HEI values related to the changes in the yield stress, ultimate tensile strength, and reduction of area. In contrast, the hydrogenation of both coated systems had detrimental effects on the value of total elongation, which resulted in an increase in the corresponding HEI value. This behavior was likely related to the earlier onset of necking during tensile straining due to strain localizations induced by the coatings’ surface imperfections. The findings from fractographic observations indicated that both studied coatings acted like protective barriers against hydrogen permeation. However, the surface quality in terms of pores and other superficial defects in the considered coatings remains a challenging issue. Full article
