Abstract

The invention relates to a method for printing aluminum-silicon carbide composite material filaments through electric arc additive manufacturing. The composite material is composed of the following materials: silicon carbide with a mass fraction of 5% to 15%, and the balance of aluminum alloy. The composite material is drawn into wire by aluminum-silicon carbide composite ingot casting, and the wire material is printed and formed by two steps. The composite material of the invention has high specific strength, specific stiffness and elastic modulus, and can be widely used in the preparation of complex structural parts in the fields of aerospace, automobiles, ships and the like.

Description

technical field [0001] The invention relates to a method for printing aluminum-silicon carbide composite material filaments through arc additive manufacturing, and belongs to the field of metal-based composite materials and additive manufacturing. Background technique [0002] Aluminum silicon carbide composite materials have the characteristics of both aluminum alloy and silicon carbide ceramics. Compared with ordinary aluminum alloys, their toughness is slightly lower, but their specific strength, specific stiffness, elastic modulus, and friction resistance are greatly improved, and their thermal expansion coefficient is reduced. , The dimensional stability is improved, so the aluminum silicon carbide composite material has great application prospects in aerospace, automobile, ship and other fields. [0003] However, due to the existence of the reinforcing phase in the material, the machining of aluminum silicon carbide composite materials is not easy, it is difficult to a...
