Abstract

<p>This investigation was carried out to find a molten salt which enables a smooth electrodeposition of tungsten. The KF-B2O3-WO3 molten salt was selected on the basis of the acid-base cooperative reaction theory. A composition of KF(67 mol %)-B2O3(26 mol %)-WO3(7 mol %) was selected as the preferred bath composition. Using a tungsten anode, smooth electrodeposits were obtained at 1123 K and at a current density ranging from 250 Am−2 to 550 Am−2 on nickel, copper, stainless steel, and mild steel substrates. When a graphite anode was used, smooth electrodeposits accompanied by dendrites were obtained. The Vickers microhardness number of the electrodeposit was 422 (load 0.49 N). The smooth electrodeposit had tendencies to form the 111 fiber texture or a mixed texture of the 111, 211 and 321 fiber textures.</p>
