The present invention provides a process for the application of high temperature coating that provide enhanced impact resistance and erosion damage for the coatings. For high temperature coating systems that provide environmental protection to silicon based ceramics, the process provides the deposition of a silicon-based bond coat on the substrate using the directed vapor deposition with plasma activation and at least one supersonic gas jet nozzle. The process provides the deposition of an EBC layer using the directed vapor deposition with the gas jet nozzle. In one embodiment, the thermal barrier layer may also contain one or more dense embedded layers which further promote impact resistance. Within the process, the particular layers, silicon bond coat, EBC layer and/or TBC layer may be deposited together or specific novel layers applied in combination with other layers deposited using prior known deposition techniques.
A process for vapor deposition onto a substrate providing impact and erosion protections for a deposition on the substrate, the process comprising:
A process for vapor deposition of an environmental barrier coating (EBC) layer onto a substrate providing enhanced impact and erosion resistance for the EBC layer, the process comprising:
A process for vapor deposition of a thermal barrier coating (TBC) layer onto a substrate providing enhanced impact and erosion resistance for the TBC layer, the process comprising:
A process for directed vapor depositions and application of a plurality of protective coatings providing enhanced impact and erosion resistance for the coatings, the process comprising:
