Embodiment Construction

[0020] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0021] A kind of corrosion-resistant Al-C of the present invention f A device for one-time compound preparation of Mg composite material components, which is characterized in that it includes: female mold 1, aluminum heater 3, extrusion barrel 6, sealing block 7, pressure controller 8, pressure head 9, gas pipeline 10, vacuum pressure Table 11, vacuum valve 12, vacuum pump 13, temperature controller 14.

[0022] The female mold 1 is placed at the bottom of the extrusion cylinder 6, and there is a transition fit between the two. The aluminum foil 2 is laid on the female mold 1, and then the fiber prefabricated body 4 is placed. Magnesium alloy 5 is placed on preform 4 . There is an upper sealing block 7 on the top of the extruding cylinder 6, which is an interference fit between the two to achieve a sealing effect. The extrusion barrel 6 is connected to a vacu...

Abstract

The present invention relates to a kind of composite preparation surface covered with aluminum foil of C f The device and method of the / Mg composite material component is a metal aluminum foil corrosion-resistant protective layer of C f / Mg composite (Al‑C f / Mg composite material) component is a one-time composite preparation method, which is used to realize the composite of "composite material" and "protective treatment" process, and change the mode of separation of composite material preparation and protective coating preparation. The technical solution is to lay aluminum foil on the negative mold in advance, and control the temperature and pressure conditions to melt the magnesium alloy and keep the aluminum foil in a solid state; realize Al-C by liquid-solid extrusion f Composite preparation of / Mg composite components.

Description

technical field [0001] The invention belongs to the field of continuous long fiber reinforced magnesium-based composite materials, and is a corrosion-resistant Al-C f A composite preparation method of / Mg composite material member, be specifically related to a kind of C with surface aluminum metal anti-corrosion protective layer f / Mg composites (Al-C f / Mg composite) components of a composite preparation method. Background technique [0002] C f / Mg composite material has a series of advantages such as high specific strength and high specific stiffness, but its poor corrosion resistance seriously restricts its application. [0003] Currently, C f The corrosion protection methods of / Mg composites are mostly based on the surface modification and protection methods of magnesium alloys. Aluminum and its alloys are often used as protective materials for magnesium alloys and their composites due to their excellent corrosion resistance. Bakkar et al. used plasma spraying an...
