Abstract
This study uncovers process conditions for the homogenization of the interface zone formed by a diffusion bonding of ZrCx (x = 1, 0.85 and 0.7) assisted by a Zirconium interlayer. The transitional metal interlayer is positioned between the ceramics mating surfaces . The ability of Zr to form a homogenous joint with ZrCx was verified for all the considered cases of ZrCx. The homogenous joint domain forms under conditions of a particular range of values of (i) the concentration of carbon vacancies in the base ZrCx ceramics, (ii) the bonding temperature, and (iii) the holding time, for a given thickness of the interlayer. The formation of a homogenous domain improves remarkably the mechanical properties of ZrCx joints. It is established that the four-point bending strength and the nano-indentation hardness of the homogenous ZrCx/Zr/ZrCx joints can be as high as that of the base ceramics.
