Abstract
Aluminium nitride (AlN) is known for its enviable qualities which include; good wear and corrosion resistance, low coefficient of thermal action, low resistivity, wide band gab similar to that of silicon and other properties. For these reasons, the use of AlN to form composite material with aluminium matrix has been employed using powder metallurgy route. Non-wetting of AlN reinforcement by aluminium matrix during sintering, however, has continued to be a subject of concerned, hence necessitating the use of magnesium as a wetting agent. In this paper, the effect magnesium addition on hardness and wear resistance properties of Al-AlN composite has been investigated and presented.
