摘要

Tungsten carbide (WC) is used as an anode in molten sodium tungstate to prepare a tungsten coating.Recovery of tungsten powder from WC electrolysis has been extensively studied, but the possibility ofmaking available Tungsten coatings is still unrealized. A theoretical analysis was first carried out, andthe feasibility of electrolysis was confirmed. Subsequently, this conclusion was also verifiedexperimentally. In this experiment, the coating was studied by regulating the cathode current density.The tungsten coatings prepared at various current densities were characterized by X-ray Diffraction(XRD), Scanning Electron Microscope-Energy Dispersive Spectroscopy (SEM-EDS), nanoindentationtests, and Laser Scanning Confocal Microscopy LSCM. The results show that at a cathode currentdensity of 70 mA·cm?2, an optimized tungsten coating can be obtained. The tungsten coating has athickness of 4.1 μm and a minimum average grain size.
