Influence of binding composition on the structure and properties of steel work-pieces obtained by injection moulding

Research output: Contribution to journalArticle

Abstract

The paper presents the results of the research analyzing the influence of binding composition on the structure and properties of the stainless steel samples obtained by injection moulding technique. It have been determined the tailored composition of binding, which provides sufficient feedstock viscosity, low porosity of work-pieces, etc. Three binding compositions polypropylene and paraffin wax have been studied: 1:6, 1:2, 2:1, respectively. Stearic acid has been used as a SAS (surface active substance). The results have shown that the binding compositions between 1:6 and 1:2 polypropylene and paraffin wax provides sufficient viscosity feedstock, dimensional stability during debinding and sintering, and the high density of the final product.
