Method for continuous fabrication of fiber reinforced titanium-based composites

摘要

A method for continuous fabrication of a filament reinforced titanium base alloy sheet is provided. The sheet is formed by first assembling a number of individual silicon carbide filaments to form a tape. The tape is passed across a drum in a low pressure plasma deposition apparatus where the surface of the drum is formed of a polished and cooled refractory metal. The tape is sprayed with a plasma spray of the titanium base alloy metal to form a sheet of such metal on the tape and on the surface of the drum. The deposited sheet including the silicon carbide reinforcement tape is removed from the drum surface by peeling. The peeled product is a composite of titanium base sheet metal which is impregnated with the filaments of silicon carbide, i.e. a metal impregnated tape.
