Abstract

The invention provides a preparation method of fiber-reinforced titanium matrix composite precursors. The preparation method comprises the following steps of: (1) using zirconic acid lanthanum to serve as a sputtering target material, using silicon carbide fibers to serve as a substrate material, conducting magnetron sputtering on the zirconic acid lanthanum to deposit on surfaces of the silicon carbide fibers, and obtaining SiC-f/La2Zr2O7 silks; and (2) using a titanium alloy to serve as the sputtering target material, using the SiC-f/La2Zr2O7 silks to serve as the substrate material, conducting the magnetron sputtering on the titanium alloy to deposit on the surfaces of the SiC-f/La2Zr2O7 silks, and obtaining a fiber-reinforced titanium matrix composite precursor SiC-f/La2Zr2O7/Ti alloy. The preparation method is simple in preparation process, high in production efficiency and strong in repeatability. The preparation method uses the zirconic acid lanthanum to serve as a separation layer to effectively protect silicon carbide fiber silks, the zirconic acid lanthanum has a good bonding performance with the silicon carbide fiber silks and the titanium alloy, and prepared fiber-reinforced titanium matrix composite precursors are good in high temperature heat stability and have good interface performances.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a preparation method of a fiber-reinforced titanium-based composite material precursor. Background technique [0002] Fiber-reinforced titanium-based composites have higher specific strength and specific modulus than titanium alloys, good high temperature resistance, creep resistance, and fatigue performance, and can be used in environments higher than 600 ° C. They are considered to be the next generation of high-thrust weight Key materials than aero-engines. At present, the research and development of fiber-reinforced titanium matrix composites in China is far behind the world level in terms of basic research and preparation technology, especially in the development and preparation technology of new high-performance barrier layers. Therefore, there is an urgent need to develop The preparation technology of the precursor of the new barrier layer with hig...
