Properties of a Lead–Antimony Alloy Fabricated by Spark Plasma Sintering of Electroerosive Powders Produced in Burning Kerosene

Abstract—The composition, structure, and properties of a lead–antimony alloy sintered from an electroerosive powder produced in burning kerosene are experimentally studied. The use of spark plasma sintering to manufacture products from the powder produced by electrodispersion of an SSu3 alloy allows us to recommend such alloys for the production of current collector plates of lead car batteries due to higher anticorrosive properties compared to the initial alloys; low porosity, which allows us to increase the contact area with lead coating to improve the adhesion; and high, for nonferrous alloys, microhardness, ensuring a long service life of lead grids.
