Abstract

Monolithic ZrB2 ceramic and ZrB2–20 vol.% SiC composite were joined to themselves using pure nickel powder. The interfacial phenomena were observed and analyzed. The joining effects were evaluated by shear strength. Resulting from the special interfacial microstructure, the shear strength of ZrB2/Ni/ZrB2 system was as high as 59.7 ± 5.3 MPa. In the ZrB2–SiC/Ni/ZrB2–SiC system, the reaction between Ni and SiC resulted in a homogeneous joint composition, which was beneficial to the joining effects.
