Structure and Properties of Electroerosion-Resistant WN–WC–W2C0.84–Ag Coatings Fabricated by a Combined Method


WN–WC–W2C0.84–Ag coatings are fabricated by a combined method, which combines electroexplosive spraying, nitriding, and electron-beam treatment. The structure, phase composition, nanohardness, Young’s modulus, wear resistance under dry sliding friction conditions, friction coefficient, electrical conductivity, and electroerosion resistance of the coatings are investigated.
