摘要：

A silicon nitride fibre-reinforced cordierite glass ceramic matrix composite has been brazed to titanium and stainless steel in argon with four different interlayer materials, copper, nickel, tungsten and a metal matrix composite (mmc). Joints were tested in shear and all but one failed in the ceramic composite. The highest strength joint, using a metal matrix interlayer to join cmc to stainless steel failed in the mmc at 106 MPa. Silver-copper eutectic braze and aluminium braze can be used to join metals to titanium-coated cmc, producing joints with low levels of interfacial defects. Some joints, however, show debonding at the edges where residual shear stresses are highest.
