SPRAYED COPPER-ALUMINUM COMPOSITE MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

There is provided a composite material, which exhibits the properties of copper alloy and aluminum alloy, and which has improved wear-resistance and seizure-resistance. By frame-spraying is prepared a copper-aluminum composite material, which consists of copper or first copper-alloy (for example Cu - Pb alloy) including at least unmelted phase and aluminum or first aluminum-alloy (for example Al - Si alloy) including at least melted phase.
