Abstract

Fe-Ni alloys were fabricated on steel substrates by means of pulse electrodeposition in sulfate solutions. The layers were electrodeposited using different peak current densities, duty cycles and frequencies. Fe contents, microhardnesses and crystalline phases were examined systematically. The Fe content in the deposit decreased and the microhardness increased with increasing duty cycle and peak current density. The pulse frequency had little effect on Fe content but led to a slight decrease in microhardness. X-ray diffraction patterns show that the crystalline phases vary with changes in peak current density and duty cycle but are barely influenced by frequency. When the peak current density or duty cycle is relatively low, crystalline Fe-Ni alloy and pure Fe phases coexist; the pure Fe phases disappear as the peak current density or duty cycle increases. At still larger peak current densities or duty cycles, crystalline Fe-Ni alloy and pure Ni phases coexist.

Pulsed electrodeposition of Ni-Mo alloys

Technical Report Nee, C; Kim, W; Weil, R

The effect of pulsing the current on the composition, internal stress, and mechanical properties of Ni-Mo electrodeposits was investigated. The molybdenum content increased with increasing peak current density and to a lesser degree with decreasing duty cycle. A reduction in the internal stresses was explained in terms of the relaxation of those due to crystallite or fine grain coalescence during the off-time and an expansion of the surface layer when hydrogen diffused into it at the start of each on-time. The mechanical properties were improved by high-frequency pulse plating. Deposits consisting of alternate layers of different composition annealed at 300more »« less

Pulsed electrodeposition. Final report

Technical Report Stimetz, C

Pulse plating of cobalt-hardened gold alloys increases the cobalt content in the alloy. At lower duty cycles, the electrodeposits become dull. Little change in the microhardness was observed between pulsed and direct current electrodeposits. The TEM and electron diffraction analyses indicated no significant difference in microstructure between pulsed and conventional gold alloy electrodeposits. Pulse plated and conventional nickel deposits have been compared for differences in morphology, mechanical properties, and microstructure. The deposits were obtained from nickel sulfamate, nickel chloride, and Watts nickel plating solutions. No significant differences were found in the direct and pulse current deposits from the sulfamate andmore »« less
Electrodeposited composite coating of Ni-W-P with nano-sized rod- and spherical-shaped SiC particles

Journal Article El-Sheikh, S; Ahmed, Y - Materials Research Bulletin

In this research, Ni-W-P-SiC nanocomposite coatings are electrodeposited from the plating solution containing suspension of nano-sized spherical- and rod-shaped SiC particles. The influence of SiC particle charge, applied current density, surfactant addition and the particle shape on the SiC incorporation rate has been studied. The phase structure, microhardness and wear resistance of Ni-W-P-SiC nanocomposite coatings were evaluated using X-ray diffraction (XRD), microhardness tester and wear test apparatus. The surface morphology of the produced coatings and worn surfaces has been investigated using scanning electron microscope (SEM). Additionally, the composite coating exhibited higher hardness and wear resistance than the pure Ni-W-P alloy.more »« less
