Magnetic Ni-Co-Fe-P alloy plating on surface of ICF glass target

Magnetic Ni-Co-Fe-P alloy plating was deposited on surface of ICF glass targets by electroless plating technology. Composition, morphology and magnetic property of the plated Ni-Co-Fe-P alloy plating were characterized by scanning electron microscopy, atomic force microscopy, energy diffraction spectrum and vibrating sample magnetometer. The results showed that the Ni-Co-Fe-P plating on surface of ICF glass targets was composed of small grains, the average diameters of which were 50 nm or so. The Ni-Co-Fe-P plated ICF glass targets had better surface smoothness and magnetic parameters than the Ni-P plated ones, and could be used in experimental research of magnetic suspension.
