Special Issue Information

Dear Colleagues,

For a continuous building of social infrastructure and economic development, environmental compatibility is a crucial requirement for the metallic structure materials used in industrial fields with high-temperature environments, such as energy conversion system (nuclear power plants, fossil fuel power plants, fuel cell system, etc.), gas turbines industry, chemical industry, etc. It is essential to validate metallic materials against high-temperature applications. In order to prevent corrosion degradation and oxidation processes, new corrosion-resistant alloys and protective coatings are needed to serve an extended lifetime for structural materials; it is important to understand the corrosion and cracking mechanism of materials performed in such extreme environments.

I am pleased to invite and welcome you to contribute to this Special Issue, titled “Corrosion and Cracking Behavior of Metallic Materials in High-Temperature Environment”. The aim of this Issue is to discuss the corrosion and cracking behavior of metallic materials and coatings applied in high-temperature environments. The topics covered include general corrosion, localized corrosion, oxidation, stress corrosion cracking, corrosion fatigue, liquid metal embrittlement, molten salt corrosion, etc. Articles which focus on material design, modification, treatment, protection, corrosion test technique, and corrosion simulation, which are relevant to the corrosion and prevention of materials, are also welcomed.

Crevice corrosion (CC) behavior of 201 stainless steel (SS) in 1 M NaCl + x M HCl/y M NaOH solutions with various pH was investigated using SECM and optical microscopic observations. Results show that the CC was initiated by the decrease in pH value within the crevice. The pH value near the crevice mouth falls rapidly to 1.38 in the first 2 h in the strongly acidic solution, while the pH value was observed to rise firstly and then decrease in the neutral and alkaline solutions. It indicates there is no incubation phase in the CC evolution of 201-SS in a pH = 2.00 solution, while an incubation phase was observed in pH = 7.00 and 11.00 solutions. Additionally, there appeared to be a radial pH variation within the gap over time. The pH value is the lowest at the gap mouth, which is in line with the in situ optical observation result that the severely corroded region is at the mouth of the gap. The decrease in pH value inside results in the negative shift of open circuit potential (OCP) and the initiation of CC of 201-SS. The increased anodic dissolution rate in the acidic solution accelerates the breakdown of passive film inside, reducing the initiation time and stimulating the spread of CC. Full article
