Abstract

A forming method of a metal matrix nanocomposite material part disclosed by the present invention comprises the following steps: step 1, pretreatment of nanomaterials and metal materials; step 2, preparation of nano-reinforced metal matrix composite light-cured slurry; step 3, Carry out photocuring forming; step 4, degreasing and sintering. The forming method of the present invention uses high-energy ultrasonic waves throughout the pretreatment of metal powder and nanomaterials, effectively reducing the agglomeration of nanoparticles during the forming process; , which increases the complexity of the formed parts; through rapid sintering at a temperature lower than the interface reaction, the nanoparticle interface reaction in the whole process is reduced; the steps are simple and have good practical value.

Description

technical field [0001] The invention belongs to the technical field of photocuring forming methods, and in particular relates to a forming method of metal-based nanocomposite parts. Background technique [0002] Due to the characteristics of high strength, good toughness, and excellent thermal stability, metal matrix nanocomposites have broad application prospects in high-tech fields such as aviation, aerospace, and automation. At present, there are two main methods for forming metal matrix nanocomposite parts: liquid casting method and solid state sintering method. The liquid casting method can obtain near-net-shape complex parts, but it requires a mold, there are interfacial reactions, and the composition is difficult to control; the solid-state sintering method is easy to control the composition, but it is prone to particle agglomeration and can only obtain simple small parts. Therefore, there is currently no method for rapid prototyping of complex metal matrix nanocompo...
