Pt-Pd system: Investigation of mechanical properties

Abstract

To extend the future application of products based on platinum and palladium, investigation of mechanical properties of Pt-Pd alloys was conducted. Binary Pt-Pd alloys are widely used in chemical industry, electronics, and in particular for the development of laboratory instruments. Following mechanical properties were examined: hardness, microhardness, tensile strength, elongation, specific electrical resistance and relative thermal expansion, rupture time and creep rate of selected alloys. Based on the obtained results it can be concluded that alloying of platinum with palladium does not lead to a significant improvement in mechanical properties, both at room and elevated temperatures.
