Electrodeposition of Amorphous Alloys

Known processes are related to those of electroless or electrolytic plating. They involve the simnltane-ous deposition of both metal and P atoms [46]. There is evidence that deposition of the latter occurs via the formation of phosphine, PH3, which then decomposes [23,47-49]. Various crystalline metal phosphides have been identified as well as amorphous phases, the extent of the latter depending on process conditions. [Pg.1073]

Patents exist for the deposition of Ni/P, Cr/P, Fe/P, Fe/Cr/P, Ni/Cr/P and other alloys which are microhard and corrosion resistant. The amorphous deposits can in many cases be rendered CTystal-line by suitable heat treatment. Electrochemically deposited thin films with compositions such as Co32Ni55RegP7, CojiNijgPy and Co34Ni59P, can be used for high-density magnetic recording devices (Section 12.19). [Pg.1074]


Amorphous and crystalline species are involved in the technology of electrodeposition of amorphous alloys. Microhard and corrosion-resistant surfaces are obtained with Ni/P, Cr/P and Fe/P systems (Section 12.8). Amorphous alloys of this type may also be involved with super black surfaces (Section 12.8). [Pg.1207]
