Preparation of amorphous-nanocrystalline composite structured Ni–P electrodeposits

The Age Hardening Mechanism of Nanocrystalline Ni-P Alloys Synthesized by Electrodeposition

“…Phosphorus increased with an increase of H3PO3, and became saturated at about 8 mass% by the addition of H3PO3 higher than 5g/l. These results are consistent with those reported by Yuan et al 19 Table 2 Plating condition. Table 1 Electrolyte.…”

Influence of pulse parameters on the microstructure and microhardness of nickel electrodeposits

“…The substrate was first chemically degreased, rinsed with distilled water, and then scrubbed with alcohol, acetone. The substrate was then acidcleaned and activated, and finally rinsed with distilled water [12]. After that, it was placed vertically in the electroplating cell of 0.5 dm 3 with magnetic stirring, parallel to the anode, with anode-cathode distance of 5 cm.…”

Examining the effect of electrosynthesis conditions on the Ni-P alloy composition

“…Essence of the method is that the orthophosphates form with the salts of vanadium and molybdenum yellow compounds with the following composition P 2 O 5 •V 2 O 5 •22MoO 3 •11H 2 O. Optical density of the solution was measured using the photocolorimeter KFK-2-UKhL 4.2 (Russia) at a wavelength of 440 nm.…”

“…Accordingly, corrosion current of Ni-P is less. Nanocrystalline precipitations with a content of phosphorus in the alloy of 5−9 % (by weight) are more corrosion resistant than the microcrystalline alloys containing a smaller amount of phosphorus [3]. Wear resistance of such alloys, compared with the amorphous alloys containing more than 9 % (by weight) of P, is better.…”
