Interfacial Properties of Bonded Dissimilar Materials Fabricated via Spark Plasma Sintering

This paper describes the characterization of interfacial properties bonded dissimilar materials for fabrication biocompatible composites and functionally graded (FGMs) with high mechanical performance. In development biomaterials conflicting such as strength toughness artificial bone, much attention has been paid to FGMs consisting ceramics metals. Their are influenced by interfaces materials, hence it is important evaluate properties. study investigated influence combinations on fracture four types materials: titanium, type 316L stainless steel, partially stabilized zirconia, alumina. The were fabricated via spark plasma sintering, which a powder metallurgy technique utilizing uniaxial load pulsed direct current in vacuum. evaluated compression-bend testing indentation testing, respectively. distributions elements near due atomic diffusion during sintering evaluated, material was considered based distributions. It found that all lower than those monolithic extent degradation dependent combinations. If occurred both sides interface, tended be relatively high.
