Titanium mesh/rod joined by pulse electric current sintering: Effect of heating rate

Abstract

Ti mesh was bonded to a solid titanium substrate using pulse electric current sintering (PECS) to fabricate a porous surface of potential use in a titanium implant. We investigated the effect of heating rate on the bonding strength, deformation of the mesh and deformation of the entire construct. During the PECS process, there was a temperature gradient between the Ti mesh and Ti rod, which increased with increasing the heating rate. At the same bonding temperature, a rapidly heated mesh showed a higher temperature than when heating was slow, and caused the strongest bonding. © 2006 The Japan Institute of Metals.
