Abstract

The research of platinum metal recovery from compound solutions including process ones with high salt content in non-ferrous and other metals is given. Effective conditions for platinum metal sorption recovery from sulphate cupronickel solutions by nitrating and anodizing methods are stated. The level of platinum family recovery is 95-99%.

Abstract

We proposed a new method, electroplating followed by spark plasma sintering (SPS), to fabricate laminated TiB 2 -B 4 C/Cu-Ni composites with high strength and high toughness. It is found that a thin intermediate Cu layer can effectively enhance the strength of the interface between the ceramics and the metals, resulting in a high flexural strength and toughness of the laminated TiB 2 -B 4 C composites simultaneously. A flexural strength and fracture toughness of 651 MPa and 11.6 MPa m 1/2 respectively, are achieved, an approximately 90% improvement over TiB 2 -B 4 C bulk. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Cupronickel was used as the electrode material to fabricate microstructures on polycrystalline diamond by electrical discharge machining (EDM). The electrodes were shaped into tiny rotary wheels driven by the flow of EDM fluid. Results showed that material removal rate was improved by a factor of five compared to conventional electrode materials. Raman spectroscopy and energy dispersive X-ray spectroscopy indicated that graphitization of diamond and diffusion-based chemical reactions between nickel and diamond dominated the EDM process. Effects of electrode rotation rate and discharge energy on the EDM characteristics were clarified. High form accuracy (∼0.5μm/1mm) and low surface roughness (∼0.1μm Ra) were obtained.
