Abstract
A process where a solid deposit is obtd. on a substrate by decompsn. or redn. in the gaseous or vapour phase, the novelty being that the energy for the reaction is provided by a carbon dioxide laser which emits a wavelength which is absorbed by the single gaseous phase. When the substrate is a conductor, an electric field is pref. applied between the substrate and the walls of the reactor. Pref. substrates are filaments or fibres of SiO2, carbon or tungsten wire, while pref. coatings are (a) B obtd. from redn. of BCl3 in H2; (b) boron carbide obtd. from BCl3, a hydrocarbon and H2, (c) BN obtd. from BCl3 and NH3. The process is suitable for coating parts subjected to violent mechanical stress.
