Properties of powdered metal-ceramic materials obtained from by-products of the mining and metallurgical industry of Uzbekistan

Abstract

One of the actual problems of production is the use of various waste products, in particular metallurgical. The method of powder metallurgy allows the use of waste from metallurgical industries. This is used in this work to obtain an antifriction porous material based on iron and copper. Iron and copper powders obtained at the Almalyk Mining and Metallurgical Combine by restoring iron and copper scale of metallurgical plants are used. Pyrite, a waste product of the Almalyk Mining and Metallurgical Combine, is used as an additive material. Tests have shown the possibility of manufacturing metal-ceramic iron and copper-containing antifriction alloys with pyrite additive based on local raw materials.
