  • Publication number: 20030035902
    Abstract: In a process for coating silicon carbide fibers with a titanium-based alloy by plasma spraying, the titanium-based alloy is sprayed onto the silicon carbide fibers by way of an electrode-free high-pressure plasma. The high-pressure plasma is generated in a microwave- or radiowave-transparent working tube with a gas inlet opening and a gas outlet opening by ignition of a process gas which has been introduced into the working tube at a pressure p≧1 bar. The plasma is maintained by absorption of microwaves or radiowaves and is passed into the working space as a plasma jet through a nozzle arranged at the gas outlet opening of the working tube.
