Abstract
Electrodeposited Ni and Ni-diamond composite layers were used as diffusion barriers for Fe to facilitate the diamond growth on stainless steel substra tes. Raman spectroscopy and scanning electron microscopy show the formation of good quality diamond crystallites by chemical vapor deposition. X-ray d iffraction results indicate that the expansion of Ni unit cell has taken pl ace due to the formation of the Ni-C solid solution. This observation is al so well supported by x-ray photoelectron spectroscopy studies. The lattice constant of the expanded Ni unit cell matches closely with the diamond, and this may be helpful in explaining the epitaxial growth of diamond on singl e-crystal Ni observed by others.
