Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Zn-Ni composite coatings on mild steel substrate were prepared by incorporating multiwalled carbon nanotubes (MWCNT) through electrodeposition technique successfully. The reinforcement of carbon nanotubes was increased by achieving high dispersion in the plating electrolyte. Surfactants namely, Cetyltriammonium bromide (CTAB), Sodium lauryl sulfate (SLS) and Triton X 100 were made use in this attempt. The coated specimens were tested for their corrosion resistance in 3.5% NaCl solution through polarization and Electrochemical Impedance Spectroscopic (EIS) studies. Surfactants deagglomerated the particles and enhanced their incorporation in the metal matrix which helped to obtain composites with higher corrosion resistance and increased hardness. 52 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The ternary alloy Ni-W-P and its WS2 nanocomposite coatings were successfully obtained on low-carbon steel using the electroless plating technique. The sodium tungstate (Na2WO4) concentration in the bath was varied to obtain Ni-W-P deposits containing various Ni and P contents. WS2 composite was obtained with a suitable concentration of Na2WO4 in Ni-P coating. These deposits were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray analysis (EDX) studies. The corrosion behavior was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) studies in 3.5 wt % NaCl solutions, and the corrosion rates of the coatings for Ni-P, Ni-W-P, and Ni-W-P-WS2 were found to be 2.571 × 10-5, 8.219 × 10-7, and 7.986 × 10-7 g/h, respectively. An increase in the codeposition of alloying metal tungsten (W) enhanced the corrosion resistance and microhardness and changed the structure and morphology of the deposits. Incorporation of WS2nanoparticles to Ni-W-P alloy coating reduced the coefficient of friction from 0.16 to 0.11 and also helped in improving the corrosion resistance of the coating further. 52 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -La aleación ternaria Ni-W-P y sus recubrimientos de nanocompuestos WS2 se obtuvieron con éxito sobre acero de bajo carbono mediante la técnica de electrodeposición. Se varió la concentración de tungstato de sodio (Na2WO4) en el baño para obtener depósitos de Ni-W-P con distintos contenidos de Ni y P. El compuesto WS2 se obtuvo con una concentración adecuada de Na2WO4 en el recubrimiento de Ni-P. Estos depósitos se caracterizaron mediante difracción de rayos X (XRD), microscopía electrónica de barrido (SEM) y estudios de análisis de rayos X de energía dispersiva (EDX). Se investigó el comportamiento de la corrosión mediante estudios de polarización potenciodinámica y espectroscopia de impedancia electroquímica (EIS) en soluciones de NaCl al 3,5% en peso, y se comprobó que las velocidades de corrosión de los recubrimientos de Ni-P, Ni-W-P y Ni-W-P-WS2 eran de 2,571 × 10-5, 8,219 × 10-7 y 7,986 × 10-7 g/h, respectivamente. El aumento de la codeposición del metal de aleación wolframio (W) mejoró la resistencia a la corrosión y la microdureza y cambió la estructura y la morfología de los depósitos. La incorporación de nanopartículas de WS2 al recubrimiento de aleación Ni-W-P redujo el coeficiente de fricción de 0,16 a 0,11 y también contribuyó a mejorar aún más la resistencia a la corrosión del recubrimiento. 52 pp. Spanisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Los recubrimientos compuestos de Zn-Ni sobre sustrato de acero dulce se prepararon incorporando nanotubos de carbono multipared (MWCNT) mediante la técnica de electrodeposición con éxito. El refuerzo de los nanotubos de carbono se incrementó al conseguir una alta dispersión en el electrolito de recubrimiento. Para ello se utilizaron tensoactivos como el bromuro de cetiltramonio (CTAB), el lauril sulfato de sodio (SLS) y el Tritón X 100. Se comprobó la resistencia a la corrosión de las muestras recubiertas en una solución de NaCl al 3,5% mediante estudios de polarización y espectroscopia de impedancia electroquímica (EIS). Los surfactantes desaglomeraron las partículas y mejoraron su incorporación en la matriz metálica, lo que ayudó a obtener composites con mayor resistencia a la corrosión y mayor dureza. 52 pp. Spanisch.
