THE BEHAVIOR OF ELECTRODEPOSITED NANOCRYSTALLINE Co–Ni ALLOYS SUBJECTED TO MAGNETIC AND STRESS FIELDS
SURFACE REVIEW AND LETTERS(2012)
摘要
Nanocrystalline materials commonly show properties superior to their bulk counterparts. Therefore, they are promising candidates used in the next generation of micro/nanodevices. In the present study, nanocrystalline Co-Ni alloys were fabricated using the pulsed electrodeposition method. The microstructures and components were examined by scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectrometer (EDX). Moreover, the magnetic properties of these alloys subjected to external stresses were studied using a magneto-mechanical coupling test system. The results obtained show that the nanocrystalline microstructure composed of ultrafine particles possessed good magnetic properties, and the saturation magnetization could reach approximately 2 T. In addition, the applied static and varying stresses did slightly affect the magnetic properties of the electrodeposits.
