Adhesion properties of tungsten and SiC ceramic-bonded carbon

A newly developed carbon-based composite, SiC ceramic bonded carbon (30 vol% SiC) was directly clad with tungsten (W) at 1700 °C by spark plasma sintering. There were no voids or cracks in the fabricated material. The adhesion strength between W and SiC/CBC is 90 MPa and 33 MPa by the bending and tensile test, respectively. The interface between W and SiC/CBC was analyzed and the cladding mechanism was discussed.
