BINNER, J.G.P. ... et al, 1995. Characterisation of the join of electric discharge pulse welded ceramics. Journal of the European Ceramic Society, 15, pp 1037-1041
A series of sialon, silicon carbide (SC) and lead
zirconium titanate (PZT) ceramics joined by an
electric discharge pulse-welding process have been
examined to provide information on joint characteristics.
Techniques used include X-ray diffraction,
scanning electron microscopy and energy dispersive
X-ray analysis. Results indicate that joints with variable
degrees of interfacial contact, interlayer porosity
and thermal stress have been produced,
depending on the precise conditions used. Titanium
was found to provide better wetting characteristics
than aluminium when used as an interlayer material.
