Abstract
A process for manufacturing metal and ceramic matrix composite materials. The invention also encompasses various composite products made by the disclosed method. The resulting composite material comprises a reinforcement material in either continuous or discrete form embedded in a matrix material which is either a pure metal, a metal alloy, or a ceramic. The reinforcing material is optionally coated with a barrier coating material. An electric arc or plasma arc is used to spray a thin layer of matrix material over a preplaced layer of reinforcement material. Successive layers are built up until a desired object shape and thickness are achieved. There is an optional final step of high-temperature diffusion annealing or hot isostatic pressing.
