Growth stages of amorphous Ni-P films deposited both by electrolytic and by chemical means were studied by electron microscopy. Nucleation and the growth of separated three dimensional grains have been proved. Comparing the shape of grains with that of computed ones different mobilities of adatoms on the surface of growing grains have been found. The mobility of adatoms is promoted in the case of electrolytic deposition. The development of structural inhomogeneities ("supernetwork") can be attributed to the coalescence of grains as well as to the limited mobility of adatoms, building the amorphous structure of the grains.
