Проведено сравнение свойств материалов сталь СПН14А7М5 -карбид титана (0-30 об.% TiC), полученных лазерной наплавкой, лазерным спе-канием и способом порошковой металлургии (прессование и спекание). Исследованы процессы структурообразования, сопоставлена твер-дость разных образцов. Установлена возможность создания материалов с улучшенными характеристиками с помощью лазерных техноло-гий, в частности, поверхностного упрочнения изделий при использовании лазерной наплавки. Ключевые слова: лазер, наплавка, спекание, плавление, сталь, карбид титана, смесь, мощность, микроструктура, твердость, прочность.Comparison of the properties of materials: SPN14A7M5 steel -titanium carbide (0-30 vol.% TiC) produced by laser building-up, laser sintering, and powder metallurgy (compaction and sintering) has been carried out. Structure formation processes are investigated; the hardness of different samples is compared. The possibility of material production with improved characteristics by means of laser processing, in particular, of surface strengthening of products when using the laser building-up is established.
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.
