Coatings from WC–Co–Cr AMPERIT®554.074 powder were deposited using a multichamber detonation device. Investigations of coating microstructure and phase composition were conducted, using scanning electron microscopy and X-ray structural analysis. Dense coatings form at spraying by this method which consist of inclusions of tungsten carbide phases, uniformly distributed in Co–Cr matrix. Coating porosity is equal to ~0.2 %, microhardness is – 10.4 ± 1.2 GPa. Experience of application of multichamber detonation device for deposition of wear-resistant coatings from WC–Co–Cr powder is shown, both at the stage of part reconditioning and at design of components of various mechanisms. 12 Ref., 2 Tabl., 9 Fig.
Keywords: thermal spraying, detonation device, hard alloy, coating, microstructure, wear, porosity, hardness, industrial application
