The invention relates to a device and a method for compositely preparing a Cf / Mg composite material member with surface coated with an aluminum foil. The method for compositely preparing the Cf / Mg composite material member with the surface coated with the aluminum foil is a one-time composite preparation method of a Cf / Mg composite material (Al-Cf / Mg composite material) member coated with a metalaluminum foil corrosion-resistant protective layer. The method for compositely preparing the Cf / Mg composite material member with the surface coated with the aluminum foil is used for realizing the compounding of a composite material and a protective treatment process, and is used for changing the mode that composite material preparation and protective coating preparation are separated in sequence. According to the technical scheme of the device and the method for compositely preparing the Cf / Mg composite material member with the surface coated with the aluminum foil, the aluminum foil is laidon a female die in advance; by controlling temperature and pressure conditions, a magnesium alloy is melted while the aluminum foil is kept in a solid state; and composite preparation of the Al-Cf / Mgcomposite material member is achieved in a liquid-solid extrusion mode.
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...
