ABSTRACT:
Light alloy articles comprising a body of light alloy having a composite layer of heat-resistant fibers and light alloy and bonded to said body, and a surface layer of heat-resisting alloy sprayed onto said composite layer exhibit improved integrity and heat resistance when the heat-resisting alloy is plasma sprayed onto one surface of a preform of fibers and the light alloy is then cast to the opposite surface of the preform such that an interfacial layer is defined between the composite layer and the surface layer in which the fibers and light alloy are integrally incorporated with the heat-resisting alloy.
