ABSTRACT:
Ceramic films and coatings, single or multi-layered, including superlattice, infiltrated with boride, carbide, nitride, oxynitride, and silicide were formed by methods which comprises of an electrochemical coating of a ceramic precursor by a constant or an amplitude-modulated electric current with a DC component in a medium containing at least one of the ionic species for the composition of the ceramic precursor, following single or multiple infiltration in a medium containing at least one of the compounds selected from a B-containing compounds, a C-containing compounds, a N-containing compounds, a Si-containing compounds, and a mixture thereof, by heating means selected from radio-frequency, microwave, thermal, flame, plasma, laser, and a mixture thereof.
