A Study of Porosity of Products Sintered from BrS30 Alloy Electro-Erosion Powders

Abstract:

The article discusses a topical issue of scrap metal recycling, in particular BrS30 alloy scrap recycling, into powders for their repeated use to fabricate and harden machine parts. Nowadays, one of the most promising method of processing any conductive material is electro-erosion dispersion, which is non-waste, eco-friendly and energy-efficient. The paper presents the findings of a research of porosity of products, sintered from leaded bronze pressed powders, obtained by electro-erosion dispersion in distilled water. It was determined that in uniaxial pressing of the powder using a desktop hydraulic press, and in isostatic pressing of the powder using an isostatic press, and further sintering of the obtained samples in a folding tube furnace, the porosity was 0.61% and 1.44%, respectively.
