PREPARATION AND ELECTROMAGNETIC ABSORBING PROPERTIES OF TIC/NI POWDERS

In order to improve the microwave absorption performance of TiC powder, TiC/Ni composite powder was prepared by coating nickel particles with mass fraction of 10%, 20% and 30% on the surface of TiC by typical coarsening and sensitizing electroless nickel plating process.The composite powder was characterized by SEM and XRD, and the effect of nickel
