Project title : Corrosion behavior of ceramic phase particle reinforced composites

This research focuses on the corrosion properties of TiB2 particles reinforced metal matrix composites (MMCs) fabricated by powder metallurgy (PM) and hot isostatic pressing (HIP) processes. The metal matrices of MMCs include Fe-based and Cu-based alloys. The yield strength of Fe-based alloys, e.g. austenitic stainless steels can be improved dramatically by the incorporation of TiB2 particles, but the corrosion resistance of such alloys is decreased accordingly. In this project, potentiodynamic and pitting scans, weight-loss measurements and surface analytical techniques will be used to study the corrosion properties of TiB2-reinforced MMCs.
