Plating Layer

To develop the new bonding method under low bonding temperature and short holding duration, pulse electric current sintering (PECS) method is applied. The Ni plating layer was used as the interlayer. The following experimental factors were researched:(1) Thickness of Ni plating layer, (2) Bonding temperature, (3) Bonding pressure and (4) Heat treatment after plating. The bonding strength of W-Ni plate-Cu joint could be obtained under low bonding temperature of 773 K and short bonding duration of 10 min.

Pulse Electric

Effect of the pulse electric current on mechanical properties of an ultra-high strength steel (UHSS) is experimentally investigated. A single pulse of electric current with a short duration of 0.36 sec is applied to the specimen under tensile plastic loading. The experimental result showed that flow stress of the UHSS nearly instantly drops at moment of electric current, following strain hardening until necking of the specimen. Uniform elongation completely depends on the pulsing strain, while ultimate tensile strength slightly changes after electric current.
