Abstract

See full text

A method for manufacturing a part by alloying a precious metal with boron, wherein: a quantity of precious metal reduced to powder form is provided; a quantity of a nano-structured micrometric boron powder is provided; the precious metal powder is mixed with the nano-structured micrometric boron powder to obtain a mixture; the mixture is compacted by applying a uniaxial pressure; the mixture is subjected to a spark plasma sintering or flash sintering treatment, or to a hot isostatic pressing (HIP) treatment, to obtain an ingot of a precious metal/boron alloy, and the ingot is machined to obtain the part, or the ingot is reduced to powder form by a micronisation treatment and the powder is treated to obtain the part. Additionally, a gold/boron alloy.
