Abstract This study analysed the influence of codeposition SiC particles with different sizes: 50 nm, 500 nm and 5 μm, type bath agitation (stirring or ultrasonic) on electrocrystallisation nickel coatings. The composites matrix microstructure was by means SEM, EBSD XRD, to evaluate grain size, crystal orientation, internal stresses benchmarked against pure samples electrodeposited in equivalen...

To improve the wear resistance of type 45 steel surfaces, Ni–Mn alloy coatings are prepared through electrodeposition under different sodium citrate concentrations based on which SiC particles varying added to prepare Ni–Mn–SiC composite coatings. The characterized by scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, microhardness testing, surface roughness meter,...

Heavy ions in materials science can be used for many applications concerning changes in composition, structure and physical properties. The modification of interfaces in bi-layer samples is frequently performed by ion beam mixing experiments [1-4]. However, the mixing behaviour of the components is much more complicated than in the earlier studied metal/metal systems, because of the more comple...

Ni-catalyzed Si-based heterostructure nanowires grown on crystal Si substrates by hot-wire chemical vapor deposition (HWCVD) were studied. The nanowires which included NiSi nanowires, NiSi/Si core-shell nanowires, and NiSi/SiC core-shell nanowires were grown by varying the filament temperature T f from 1150 to 1850 °C. At a T f of 1450 °C, the heterostructure nanowires were formed by crystallin...
