Intorduction Alumina ceramics have already found wide applications in wear resistant components such as journal bearings, valve seats, piston rings in automotive engines and mechanical seals [1-2].
The development of metal-reinforced ceramics has produced a group of materials which utilize the novel concept of ductile particle crack bridging of a brittle matrix phase to produce a number of attractive properties for structural application.
Experimental procedure Alumina powder with an average particle size of 200 nm and nickel particle with a particle size of 2 µm were used as starting materials.
