Development of Nickel Boron Alloys for Brazing Materials

  • Chapter
Ni-Co 2013

Abstract

Nickel-base filler materials are generally used in applications where resistance to corrosion and heat resistance required. Their description as high-temperature brazing filler materials is amply justified. In this study, nickel boron (NiB) alloys is produced via carbothermic reduction starting from boric acid (H3BO3) together with high purity nickel (NiO), charcoal and sawdust by using DC arc furnace which the boron-containing composition of the basic metal is tapped at the bottom. In the arc furnace experiments, different starting mixtures were carried out, and optimum starting composition for producing 15–20 wt. % B containing NiB alloys were investigated. Alloy compositions, metal recoveries, graphite electrode and energy consumptions were performed. The obtained products were characterized by using wet chemical analysis (AAS/ICP), XRD and SEM/EDS techniques.
