- Title
TUNGSTEN CARBIDE BASED CLADDING MATERIALS.
- Authors
ZHUDRA, A. P.
- Abstract
The paper presents materials for cladding by composite alloys based on tungsten carbides. Brief description of the technology of producing special cladding hard alloys of type, macrocrystalline tungsten carbide, fused tungsten carbide WC + W2C with crushed, surface-melted and spherical granules is given. Process schematic and unit for thermocentrifugal sputtering of refractory compound ingots with application of plasma arc as the heat source is described. Comparative data are given on hardness, chemical and stoichiometric compositions of tungsten carbide granules produced by different technologies. Macrostructures of composite layers, produced by the method of plasma-powder cladding, are shown. Schematic and macrostructure of a layer produced by the method of induction furnace impregnation is given. Commercial grades of powders of fused tungsten carbides in spherical granules and main grades of strip relit are presented. 22 Ref., 3 Tables, 8 Figures.
