Corrosion Mechanism for Copper Sulfide Formation Induced by Dibenzyl Disulfide in Oil-Immersed Insulation

IEEE Access, 2019
This paper investigated the influence of paper-wrapped on the deposition of sulfur corrosion on the insulation winding (paper-wrapped copper conductor) in oil-immersed insulation containing dibenzyl disulfide (DBDS).

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Multi-scale evaluation of crevice corrosion behavior in two lean duplex stainless steels: from initiation to propagation

Corrosion Communications
This paper evaluates crevice corrosion behavior of lean duplex stainless steels (DSS) 2002 and 2101 using refined methods. DSS 2002 exhibits lower critical conditions, while DSS 2101 exhibits faster propagation.

Adherence of Carbon Steel Rust on the Corrosion of an Austenitic Stainless Steel Bolt in Marine Atmosphere

International Journal of Electrochemical Science, 2014
Stainless steel fasteners can fail as a result of stress corrosion cracking (SCC) in coastal atmosphere. In order to have a better understanding of the development of stainless steel fasteners’ SCC in marine atmospheric, the corrosion electrochemistry ...

Mechanistic Control of C─H Bond Activation and C─C Coupling in Light‐Driven Methane Conversion to C2+ Products over Multifunctional Photocatalysts

Advanced Functional Materials, EarlyView.
Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

Role of crevice size induced microenvironment variation within the gap in initiating crevice corrosion of 201 stainless steel

Frontiers in Materials
The effects of the real-time changes in the microenvironment within the crevice caused by the change in crevice size on the induction of crevice corrosion of 201 stainless steel (201-SS) in 1 M (pH = 4.00) NaCl solution were evaluated using conventional ...

Analysis of corrosion damage in a boiler made of AISI 304L stainless steel

Zaštita Materijala, 2014
The corrosion damage near the welded joint in the boiler of AISI 304L stainless steel was analysed. During welding, heat tint was formed near the weld on the inner surface of the boiler, because shielded gas was not applied.
