A new carbon plus silicon carbide (C+SiC) alloy material has been developed for use on in-vessel components of plasma devices. This material is nominally 10 wt. % SiC and is applied as a coating to graphite substrates. It has been tested in the limiter/beam armor position of Doublet III for over 11,000 plasma shots. The performance is excellent and the material is highly resistant to thermal shocks, thermal cycling, and erosion from plasma boundary and neutral beam interactions. This promises a long useful life for components in fusion vesels.
