This article is a continuation of the series devoted to the creation and application of nanomaterials and nanotechnologies in modern industry in general and in metallurgy, materials science and foundry production in particular. The article deals with the choice of equipment and the development of effective methods for obtaining nanomaterials. Examples of the application of the developed equipment, technologies and materials obtained in the Republic of Belarus and abroad are given.
The third article of the series devoted to the application of nanomaterials and nanotechnologies in industry in general and, first of all, in metallurgy, materials science and foundry is presented. This article deals with the use of nanomaterials for the improvement of ferrous and non-ferrous alloys by micro-alloying and modifying methods, as well as the synthesis of new composite materials. The results of research on C-B-Fe composites obtained at the Belarusian State Technological University, a method for modifying gray cast iron with micro-additives of abrasive slurries of high-speed steels, proposed by specialists of BNTU and OJSC «MTW», and aluminum alloys modified with nanostructured carbideand nitride-containing powders developed by Belarusian, Bulgarian and Russian scientists are presented.
The article is devoted to a special nanostructured form of carbon – fullerenes; the discovery of which became one of the most important events in the field of physics in the 80s of the last century. The article discusses the issues of obtaining and using fullerenes and other nanostructured materials; including hybrid ones; in foundry and metallurgical production: for modifying casting alloys; binders and auxiliary molding materials; for obtaining ceramic and hybrid nanocomposites; and for other purposes. It also provides information on the creation and operation of the world’s leading research centers specializing in the synthesis and application of nanomaterials in metallurgy and foundry.
The results of research on working conditions and labor safety assessment in foundries are presented. The production factors of working conditions in foundries with different types of production and their impact on injuries and professional incidence of workers are considered. Recommendations to improve working conditions and reduce their impact on foundry workers are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
