ABSTRACT
Purpose. To conduct a comparative economic analysis of cermet alloys regeneration technology to identify the most “environmentally friendly” and cost-effective processing of solid alloys waste.
Methods. As a research technique current article considers analysis of current methods of tungsten cobalt hard alloys regeneration: pyro and hydro metallurgical, chemical (chlorine, zinc), thermochemical and using explosion energy of blasting explosives.
Findings. WA comparative economic analysis or cermet alloys regeneration technologies was conducted.
Originality.Fundamental way of shock wave treatment to stimulate destruction of powder product of any configuration in order to obtain a high quality powder for further formation, sintering and tool manufacturing of multiple use is demonstrated; ecologically friendly technology of hard alloys and cermet components of outdated military hardware and ammunition recycling.
Practical implications.. Industrial mastering of the developed technology allows to solve the following issues: – utilizing super hard metal and alloys scrap subsequent regeneration, which ensures significant savings of strategic raw material; – the use of new technology, which excludes ineffective ways of scarce raw materials working and manufacturing products as per international standards; – gradual reduction of import in favor of hard alloys cermet tools; – reduction and subsequent cut down of strategic metals and alloys scrap export, shifting towards export of readymade products – powders and tools, which will significantly increase foreign currency earnings in the country.
Keywords: : tungsten, cobalt, tool, hard alloy, cermet, recycling, heterogeneous medium, defect formation
