Abstract

The invention discloses a metal matrix composite material processing device and method with regular distribution of particles, including a shell part and a workbench installed inside it, a particle foam template delivery system, a powder material delivery system, an integrated laser system, and a computer Control system and inert shielding gas system, the computer controls the laser emission through the laser controller according to the input composite material model, sinters the raw material powder sent into the working cylinder, and controls the driver to send the plastic foam template containing particles to the work station In the corresponding area of ​​the laser sintering process, the remaining particles of the plastic foam decomposed at high temperature and the raw material powder are sintered together, so that the metal matrix composite material with the same structure as the model in the computer can be obtained through layer-by-layer processing. The invention controls the particle distribution parameters and structural size in the composite material by controlling the particle interval, size and shape in the plastic foam, and the processed particle reinforced composite material has excellent bonding strength.

Description

technical field [0001] The invention relates to a metal matrix composite material processing device and method with regular particle distribution. The metal matrix particle reinforced composite material with special structure is processed by using the laser layer-by-layer processing technology. Background technique [0002] With the vigorous development of national aviation, aerospace, automobile, military and other sophisticated fields, the performance of materials seriously affects the performance of machinery and its components. Metal matrix particle reinforced composites not only have the excellent characteristics of high specific strength, high specific stiffness, low density and controllable expansion, but also have excellent friction properties, vibration reduction, self-lubrication and other characteristics. Particle-reinforced composite materials are increasingly used in various fields. The structural parameters of the particles and the distribution parameters in t...
