Abstract
The electrochemical deposition of coatings of double tungsten and molybdenum carbides from tungstate–molybdate–carbonate melts is investigated. The composition of formed coatings is investigated by X-ray fluorescent and X-ray phase analyses. The crystal size and coating thickness are determined using scanning electron microscopy. Optimal deposition parameters of W2C · Mo2C coatings are as follows: the melt composition is Na2WO4–(1.0–4.0 mol %) Li2WO4–(1.0–4.0 mol %) Li2MO4–(1.0–5.0 mol %) Li2CO3, the cathode current density is 750–1500 A/m2, the process temperature is 1123–1173 K, and the electrolysis duration is 4 h.
