DURCH SILIZIUMKARBIDFASERN VERSTAERKTE TITANALUMINIDMATRIX MIT VERMINDERTER RISSNEIGUNG

摘要

A method for forming a composite having a matrix which is stronger and which is resistant to cracking is disclosed. The composite is reinforced by silicon carbide fibers. The silicon carbide fibers are first RF plasma-spray coated with a niobium metal and the matrix metal of titanium base alpha-2 crystal structure is next RF plasma-spray deposited over the niobium coated SiC fibers to form a layer of Ti base metal reinforced by SiC fibers. A plurality of layered structures are consolidated by heat and pressure into a composite structure.
