- Abstract
We investigate processes for obtaining composite materials with hard granules of refractory compounds and alloys (TiC, ZrC, VC, NbC, Cr3C2, Mo2C, WC (relit), carbides) and self-fluxing iron based alloys to work under abrasion and shock loads conditions. We show the dependence of the structure and properties of the materials studied on their qualitative and quantitative composition. The dependence of the structure, density and hardness of composite materials obtained from the content of self-fluxing alloy of preparation of granules impregnated carcass of hard refractory compounds and alloys. We show that the materials density fully obtained at the self-fluxing alloy content is by 10 % more than necessary to fill the voids formed by granules during their free filling in the form. The material density also depends on the wetting degree of the self-fluxing alloys TTC of the molten material under other conditions. Hardness depends on the CM component content and impregnation time. The highest hardness values are valid for compositions with an average grain size of 257 microns TTS, SFF Content, which is 10 % above optimal settlement, as well as the impregnation time, which is more than 20-30 minutes.
