Deskripsi

Fe - Al intermetallic compounds (mainly refers to FeAl and Fe3Al) have attracted extensive attention due to the low cost, melting point close to cobalt, high strength - weight ratio, excellent corrosion and oxidation resistances, etc. In this paper, the methods of preparing Fe - Al based composites and their coatings using ceramic particles as the reinforcement phase as well as the high temperature friction and wear mechanism were introduced. The related research results showed that the ceramic reinforcement phase could not only improve the mechanical properties of Fe - Al based composites and their coatings, but also significantly improve the high temperature friction properties of the composites.
