摘要：

Nanocomposites consisting of a nanocrystalline Ni matrix (grain sizes 15-20 nm) reinforced with sub-micron size SiC particulates up to 3 wt.% have been produced by pulsed current electrodeposition. Microhardness values were about two times higher than those for comparable polycrystalline Ni-SiC composites, primarily due to the hard nanocrystalline Ni matrix. (C) 2002 Elsevier Science B.V.
