Abstract:
1. A method for coating a substrate, the method comprising: reacting a flowing reactant stream initiated as a flow from a reactant nozzle by directing a radiation beam at the reactant stream to produce a product stream downstream from the radiation beam, wherein the reaction is driven by photon energy from the radiation beam wherein the reactant stream comprises a metal species or a metalloid species, wherein the radiation beam is directed to pass adjacent the substrate and wherein a concentration of product is selected to be sufficiently low to result in the deposition of coating compositions that have not coalesced into stable particulates to form a selected coating density; and directing the product stream at a substrate selectively positioned in the flow to coat the substrate with a coating material from the product stream at a density of at least about 65 percent of the density of the fully densifled coating material wherein the depositing of the coating material comprises moving the substrate relative to the flow of the product stream.
