Abstract

This study reports the corrosion resistance of novel metal matrix composites (MMCs) based on aluminium (Al) and the reinforcing component – 8.8 and 14.7 vol.% aluminium nitride (AlN) labelled as Al10AlN and Al16AlN. In humid environments the corrosion rates of Al10AlN and Al16AlN were below 0.001 mm/year, showcasing a high level of corrosion resistance. In artificial acid rain, their stability persists – corrosion rates staying below 0.005 mm/year. This high corrosion resistance in adverse conditions, makes Al-AlN MMCs well-suited for applications where durability is of utmost importance.
