摘要

The structure of electroless nickel-boron with a boron content around 5 wt.%was investigated in the as deposited and heat treated states by X-ray diffraction and by transmission electron microscopy on thinned cross-sections prepared by focused ion beam technique.

In the as-deposited state, the presence of areas with short range order has been observed. This shows that electroless nickel-boron coatings with high boron content are not fully amorphous, as is usually stated.

After heat treatment, the structure of electroless nickel-boron appeared constituted of nanocrystalline nickel-boride Ni₃B.
