In this work, an attempt has been made to synthesize a novel heterostructure nanocomposite, C/Ru@NiO-CuO (CRNC) which is suitable for energy storage application. It was chemically synthesized at high-temperature conditions, whose structural features and surface chemistry were characterized by various analytical tools. The CRNC nanocomposite reveals the nanospherical morphology with highly crystalline heterostructure, leading reliable electrode material-preferred advantages such as good...
Abstract Influence of composition, specifically manganese and nitrogen content, on the microstructure associated corrosion resistance property newly developed stainless steel has been studied. The steels have characterised for their microstructure, mechanical electrochemical properties. results indicate that addition as a substitute nickel favours austenite higher yield strength (>350 MPa), tensile (>700 elongation superior Charpy V‐notch impact toughness obtained from tests such...
In this study, a 3D-prinited solution-flow type microdroplet cell (SF-MDC) is employed as new technique for the fabrication of porous anodic aluminum oxide (AAO) layer using oxalic acid electrolyte on aluminum. The surface morphology AAO film was characterized by scanning electron microscope. aim study to fabricate through-hole alumina in single step anodizing process and investigate influence anodized voltages speeds thickness pore structure layer. results showed that diameter interpore...
The Ti was immersed in 0.058 mol/L NaF containing 1.68 H2SO4 solution with different metal cations (Ca2+, Cu2+, Fe2+, Mg2+, Mn2+, Ni2+, Zn2+, Al3+, and Fe3+) for 7 d to identify the role of on corrosion behavior titanium. To elucidate acid solution, standard electrode potential, E0, hardness cations, X, metal-fluoride complex stability constant, Kn, were chosen as potential indicator. It is found that mass loss fraction obtained from immersion tests a function has highest correlation...
Corrosion is a major problem faced by the automobile industry. To overcome corrosion, industry relies on surface coatings in which metallic (Zn, Cr etc.) and polymeric (polyurethane, epoxy, are widely recommended. However, currently smart, self-healing considered to be state of art option inhibit cut-edge corrosion enhance life-time. The direct introduction inhibitors into any matrix creates undesirable effects, majorly integrity inhibitor with spontaneous release. Hence, loading suitable...
Advanced high-strength steels (AHSSs) are widely used in the automotive industry as they possess high strength-to-weight ratio. This allows designing light vehicles with better passenger safety, lower fuel consumption, and CO 2 emissions. Dual-phase (DP) very attractive among AHSSs because of their optimal combination tensile strength (up to 1.2 GPa), ductility (10 % or more), good formability due two-phase microstructure (ferrite martensite). However, use DP steel is associated an increased...
The current study investigates the influence of pre-strain (un-strained, 3%, and 6% engineering strain) in-situ tensile stress (50%, 110%, 125% yield (YS)) on hydrogen diffusion trapping behaviour in DP 980 steel. Electrochemical permeation tests were conducted using a custom-built Devanathan-Stachurski (DS) cell integrated with horizontal tensometer. results showed that value apparent coefficient (D app ) decreased from 5.4 ± 0.1 to 3.8 0.029 × 10 -7 cm 2 s -1 , while trap density (N T...
