Abstrakt: A study was made of the electrical conductivity of WC-base detonation coatings at 20–900°C. It is demonstrated that such spray-deposited coatings have a laminar structure, which accounts for the anisotropy of their conductivity. Phase changes occurring in a coating affect mainly its conductivity measured in a direction perpendicular to the deposition axis. Data on anisotropy of conductivity can be utilized for assessing the degree of particle deformation.
