Influence of Electrolysis Parameters on Mo and W Coatings Electrodeposited from Tungstate, Molybdate and Tungstate-Molybdate Melts

Abstract

Molybdenum and tungsten coatings electrodeposition from halide-oxide and oxide melts has been realized. The influence of electrolysis conditions on physico-chemical properties of deposits has been studied. Coating structure control has been realized with the help of change of atmosphere composition above the bath and application of non-stationary current regimes during electrodeposition.

Preparation of MoB2 Nanoparticles by Electrolysis of MoS2/B Mixture in Molten NaCl-KCl at 700 °C

“…7 In order to further reduce the preparation temperature, solid-state metathesis (SSM) process was proposed to prepare molybdenum borides using MoCl 5 and MgB 2 at above 800 °C, 8 which is by far the most common and effective method for preparing molybdenum borides nanoparticles. 8,14,[16][17][18][26][27][28][29] There are also some other methods for preparing molybdenum borides, such as chemical vapor deposition 10,30 and detonation spray process 31 to prepare molybdenum borides films on Mo foil, MoAlB precursor etching treatment to synthesize lamellar MoB, 9,32 borothermal reduction of molybdenum oxide 2,33 and electrodeposition in molten salt 20,[34][35][36][37][38][39] to synthesize several molybdenum borides (Fig. 1).…”
