Abstract

Reliable Si₃N₄/Si₃N₄ joints is successfully prepared in air using pure Al filler. The interfacial microstructure, phase composition and mechanical properties of the joint are investigated in detail. The effects of joining temperature on joint structure and mechanical properties are studied. The experimental results indicate that the diffusion occurs at the interface between Si₃N₄ ceramics and Al filler. A maximum shear strength of ~42 MPa is obtained for joints joining at 950 °C for 1 h. The work makes an attempt on the joining of Si₃N₄ ceramics in air, which broadens the joining method of Si₃N₄ ceramics.
