Abstract
Spark Plasma Sintering (SPS) is a process that has simulated worldwide interest for the rapid consolidation of powder-based materials through the combined effects of electric current and pressure. Recently the localization of SPS has been realized through Current activated tip-based sintering (CATS) where ultra-high electric current densities can be applied to small targeted regions of a powder bed through a precision controlled electrically conducting tip. This unique process has been recently used to produce macro as well as micro-scale sintered features for different systems such as metallic and intermetallic powder compacts.This poster will highlight recent advancements in research on CATS.
