- Аннотация: It is established that potassium ions facilitate expansion of the current density range where crystalline alloy deposits form. This is presumed to be connected with an increase in the hydrogen overvoltage, in connection with which alloy deposits turn amorphous at higher current densities and potentials corresponding to these, at which hydrogen evolution accelerates. A high alloy deposition rate and a sufficiently negative potential of its deposition are conditions not sufficient for transition from large-crystal to nanocrystalline and amorphous deposits. Here, a more important role is played by hydrogen that inserts itself into the crystal lattice. As one could assume, hydrogen in this case facilitates preservation of the emerging nonequilibrium structures, hindering crystallization processes as a result the iron hydride formation.
