7/1/2017 · Electrodeposition of Ni-Mo alloy coatings The Ni-Mo electrolytic bath has been prepared from analytical grade reagents (Merck, India) using double distilled water. Here, nickel sulphate (NiSO 4 ·6H 2 O) and sodium molybdate (Na 2 MoO 4 ) were used as a source of metal salts and tri-sodium citrate (Na 3 C 6 H 5 O 7 ) as complexing salt.
7/1/2008 · The electrodeposition of the Ni–Mo alloys was performed in a beaker at 60 °C with the counter electrode being Ni foil placed close to the walls of the beaker. The working electrodes (Ni meshes) were placed in the middle of the electrolyte and the electrolyte was stirred with the magnetic stirrer during the alloy electrodeposition.
3/1/2019 · The electrodeposition of Ni Mo Cu coatings from roasted nickel matte precursor in ChCl-urea DES has been systematically studied. The electrodeposition process of Ni Mo Cu coatings has been revealed by CV tests. The HER performance parameters and hydrogen evolution kinetics of the coatings have been investigated by LSV and EIS experiments.
2/1/2019 · In the present study, micron-sized alumina particles as the reinforcement and molybdenum as the alloying element were incorporated in a nickel matrix during the electrodeposition process, developing Ni-Mo/Al 2 O 3 nano-composite coatings. The structure, hardness, wear, and corrosion properties of the fabricated coatings were investigated as a.
electrodeposition of Ni- Mo was tried from electrolytes of different complexing agents e.g. acetate, tartarate, pyrophosphate, citrate and ammonia but only citrate and pyrophosphate seem to be the most promising with respect to quality, adhesion and mechanical properties [5, 18].
Abstract. Ni-Mo nanocrystalline deposits (7–43 nm) with a nodular morphology were prepared by electrodeposition using direct current from citrate-ammonia solutions . They exhibited a single Ni-Mo solid solution phase. The size of the nodules increased as electroplating current density increased.
