Special Issue Information

Dear Colleagues,

Since the milestone of graphene isolation in 2004, two-dimensional (2D) materials with a nano-sized thickness have been extensively studied as a promising platform for the creation of new technologies. Advances in 2D materials have gained substantial developments in terms of materials synthesis, characterization, and functionalities: A variety of synthesis methods like mechanical or liquid exfoliation, chemical vapor deposition, and wet chemical techniques have been proved to create and even largely produce diverse 2D materials including graphene, hexagonal boron nitride (h-BN), transition metal dichalcogenides (TMDCs), phosphorene, Xenes and others; Multiple characterization methods such as scanning probe microscope, scanning transmission electron microscopes, synchronized radiation, and others have revealed many unique and unprecedented properties of 2D materials and the underlying structure-property correlations, for example, the interface or defect effect. In this special issue, “Advances in 2D/Thin Film/Interface Materials: Synthesis, Characteristics and Functionalities”, multi-/interdisciplinary studies on 2D materials including synthesis, characterization, and defects or interface-engineering of 2D materials, as well as their applications in fields of energy (e.g., batteries, capacitors, solar cell, catalysis, water splitting, etc.), water (e.g., wastewater treatment, desalination, etc. ), electronics (e.g., optoelectronics, spintronics, topological insulators etc. ), medicals (e.g., drug delivery, lab-on-a-chip, biosensor, etc.) and so on are encouraged.

A Ni-Cr alloyed layer was prepared on the surface of Q235 steel using double-glow plasma surface alloying (DGPSA) technology and the alloyed layer was cold-rolled with different deformation rates. The microstructure, composition distribution and phase composition of the alloyed layer were characterized using a scanning electron microscope (SEM), an energy dispersive spectrometer (EDS), X-ray diffraction (XRD) and an electrochemical workstation. On this basis, the corrosion resistance of the alloyed layer was analyzed. The results showed that a Ni-Cr alloyed layer formed on the surface of Q235 steel following double-glow plasma nickel–chromium alloying. The alloy elements of Ni and Cr were distributed in a gradient from the outside to the inside and the main phases were FeCr0.29Ni0.16C0.06, Cr23C6 and γ solid solution. The alloyed layer, once cold-rolled with different deformation rates, underwent synchronous plastic deformation with the substrate, with no fracturing and spalling. The self-corrosion potential of the cold-rolled specimens in 5% H2SO4 and 3.5% NaCl solution is close to that of 304L stainless steel, and the corrosion currents are much lower. The corrosion resistance of the cold-rolled specimens is comparable to the original specimens, with no significant changes. Full article
