In cookware industry, interior spray coating process is an important process to protect the cookware product from the corrosion. In this process, the coating material “TEFLON” is used to spray to cover all the part’s surface. If a pot or pan is not too deep, one spray gun is enough to spray to cover all the interior surface. However, for the high side-wall pot, two spray guns must be used to sp...

Preparation of microfibre constructs of collagen by electrospinning has been problematic due to the instability of collagen in volatile solvents, such as 1,1,1,3,3,3-hexafluoro-2-propanol, so that electrospinning leads to a substantial amount of gelatin fibres. In the present study we have demonstrated the production of collagen-based microfibre constructs by use of a layer-by-layer coating pro...

respectively. It has been reported that coating of a thin MgO layer on SnO2 particles results in enhancement of both solar cell performance and catalytic activities. The promoting effect of MgO layer was owing to barrier effect where MgO acts as a barrier layer for charge recombination. We noticed negative shift of flatband (FB) potential of SnO2 with the increase of pH values and coating of a ...

Novel composite coatings were fabricated on 6061 aluminum alloy substrates by two steps combining micro-arc oxidation (MAO) plus electroless copper plating (Cu). Different MAO + Cu compared. continuously and evenly covered an oxide surface during processing thus changing the topography. The adhesion of coating was tested pull-out method. best strength can reach industrial requirements. effects ...

Dispersion of 2D carbon nitride (C3N4) nanosheets into a nickel phosphorous (NiP) matrix was successfully achieved by ultrasonication during the electroless plating of NiP from an acidic bath. The morphology and thickness, elemental analysis, phases, roughness, and wettability for as-plated and heat-treated nanocomposite were determined by scanning electron microscopy, energy-dispersive X-ray s...

Hybrid Ni/Al foams were fabricated by depositing electroless Ni-P (EN) coatings on open-cell Al foam substrate to obtain enhanced mechanical properties. The microstructure, chemical components and phases of the hybrid foams were observed and analyzed by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD), respectively. The mechanical proper...

Conventional electroless nickel–boron deposits are produced using solutions that contain lead or thallium, which must be eliminated due to their toxicity. In this research, were in a stabilizer-free bath does not include any toxic heavy metal. During processing, the plating rate increased from 10 14.5 µm/h by decreasing concentration of reducing agent, leading stability. The thickness, composit...

Titanium alloys are widely used in many industrial applications, from aerospace to automotive, and defense medical, as they combine superior properties such high strength low density. Still, titanium its insufficient environments with friction wear because of their weak tribological properties. In the literature, numerous research works on improving surface quality have been conducted. Electrol...
