The matrix is an alloy having an alpha-2 crystal form. The matrix is reinforced with silicon carbide filaments. To reduce the tendency of the matrix to form cracks due to the brittle nature of the interface with the SiC filaments, the surface of the filaments is coated with a beta phase stabilizer composition. Such a composition contains at least one element selected from the group consisting of Mo, Cr, W, Ta, Pd, Nb, Ag, Zr, Hf, V, Re, Ir, Mn, Fe, Co, Ni, Cu, Pt, Au, and Sn.
대표청구항▼
A reinforced structural member which comprises, a matrix of a titanium base alloy having an alpha-2 crystal structure, an array of reinforcing silicon carbide filaments in said matrix, a coating of a beta-phase stabilizer selected from the group consisting of Mo, Cr, W, Nb, Ta, Ir, Pd, Pt, Zr, Hf, R
A reinforced structural member which comprises, a matrix of a titanium base alloy having an alpha-2 crystal structure, an array of reinforcing silicon carbide filaments in said matrix, a coating of a beta-phase stabilizer selected from the group consisting of Mo, Cr, W, Nb, Ta, Ir, Pd, Pt, Zr, Hf, Re, V, Ag, Mn, Fe, Co, Ni, Cu, Au, and Sn, on said filaments, and said coating being interdiffused with said matrix to provide a beta-phase stabilized diffusion zone which is substantially free of cracks. The method of reducing cracking at the interface of a silicon carbide filamentary reinforcement and a titanium base alloy matrix having alpha-2 crystal form which comprises, depositing on the surface of the reinforcing filaments prior to assembly a coating of a beta-phase stabilizer metal, plasma spray depositing the matrix onto said filamentary reinforcement, and consolidating the filamentary reinforcement into said matrix by heat and pressure.
Franchet,Jean Michel; Klein,Gilles, Process for manufacturing a bonded sheet composed of ceramic filaments with a metal matrix, device for implementing said process, bonded sheet obtained by said process.
