Abstract
A composite material of a ferrous cladding material and an aluminum cast matrix which composite material exhibits excellent performance and a method for producing the same which can be carried out quite easily. The composite material comprises a ferrous cladding material, powder particles bonded to the ferrous cladding material, seizing portions defined by the powder particles, and a cast matrix of aluminum or its alloy held by the seizing portions. The method comprises the steps of spreading powder particles over a ferrous cladding material, bonding the powder particles to the ferrous cladding material by sintering, and casting aluminum or its alloy over the sintered surface. Further, a metallic layer can be formed between the bonded powder particles and the cast aluminum, by plating.
