Abstract
A method of casting a copper based composite which includes a second phase ceramic particles. A copper or copper based alloy containing a eutectic reactive element is spray cast with the ceramic particles being injected into the spray cast stream of material prior to its being deposited onto the moving substrate. The eutectic reactive element diffuses into the ceramic particles and provides a good bond between the copper based matrix and the second phase ceramic particles. The ceramic particles may be selected from the group consisting of oxides, borides, nitrides, carbides and mixtures thereof. The eutectic reactive materials may include zirconium, chromium, titanium, aluminum and magnesium.
