Synthesis of a (Pbx, Fey, Cz) Oe matrix composite
View through CrossRef
Abstract
A (Pbx, Fey, Cz) Oe matrix composite was synthesized by mixing the powders of pure lead (Pb), pure iron (Fe), graphite (C) and pure nickel (Ni) under atmospheric pressure at a maximum temperature of 1530℃.The mixture of pure lead, pure iron, graphite and pure nickel can be used as a new kind of brazing materials for alumina ceramics. The phase composition, cross-sectional microstructure, hardness, ferromagnetism and insulating properties of the (Pbx, Fey, Cz) Oe matrix composite were analyzed by means of scanning electron microscope (SEM), energy dispersive spectrum (EDS), optical microscope, Vickers hardness tester, X-ray diffractometer (XRD), a permanent magnet and a multimeter. The (Pbx, Fey, Cz) Oe matrix composite exhibits favorable wettability with the alumina ceramic and is bounded to the alumina ceramic through an interface and is composed of the (Pbx, Fey, Cz) Oe matrix composite, PbO and Fe3O4. The (Pbx, Fey, Cz) Oe matrix composite belongs to ferromagnetism and insulating material with 301Hv.
