Abstract

The invention relates to a light-cured 3D printing metal-ceramic composite material part and a preparation method thereof. The preparation method comprises the following steps that after metal powder subjected to surface activation treatment and ceramic powder subjected to surface activation treatment are mixed, a surface curing agent and a surface polymerization initiator are added into the mixture, and a coating step is carried out; a product obtained in the coating step is subjected to aftertreatment, and a core-shell material with the metal powder as a core and a ceramic coating layer as a shell is obtained; a 3D printing thick solution material is prepared from light-cured resin, a photoinitiator, a dispersing agent and the core-shell material; the 3D printing thick solution material is subjected to curing forming through light curing 3D printing equipment, and a light curing 3D printing biscuit is obtained; and the light curing 3D printing biscuit is subjected to degreasing and sintering treatment to obtain the metal-ceramic composite material part. The dispersion and ultraviolet curing characteristics of the metal powder in the photosensitive resin are improved by a simple process, so that the metal-ceramic composite material part with excellent performance is prepared by a light curing 3D printing technology.

Description

technical field

[0001] The invention relates to the technical field of additive manufacturing, in particular to a light-cured 3D printed metal-ceramic composite material and a preparation method thereof. Background technique

[0002] With the development of science and technology, modern mechanical equipment parts are required to have higher wear resistance and mechanical strength, and at the same time, mechanical parts are also required to have complex, thin-walled, and porous structures to meet more harsh service environments. my country's raw material industry has a huge scale, some industries have overcapacity, and constraints on resources, energy, and the environment are increasingly intensified. It is urgent to vigorously develop new technologies for material processing, accelerate the transformation and upgrading of the material industry, and cultivate new growth points. It is necessary to vigorously research and develop key technologies for special metal functional m...
