Influence of Liquid Composition and Discharge Energy on Process Performance, Composition, and Properties of Particles Formed During Electric Discharge Erosion of WC-5TiC-10Co Alloy

Increasing the hardness and wear resistance of powder alloys coatings through use ultrafine-grained powders metastable phases is a promising way in metallurgy. This paper presents results studies process obtaining ultrafine by electric discharge erosion cemented carbide waste WC-5TiC-10Co on special installation. An empirical model that describes dependence productivity energy properties liquid provided. The chemical phase compositions obtained composition used specific consumption has been investigated. effect morphological average particle diameter examined. It revealed formation solid solution (W, Ti)C decrease concentration cobalt induce an increase resulting spherical particles from 1410HV0.05 to 2540HV0.05.
