The invention provides a light high-strength composite material which comprises a ceramic deposition layer and a metal deposition layer which are alternately deposited, the metal deposition layer is formed by melting and depositing metal particles through laser, and the ceramic deposition layer is formed by melting and depositing ceramic particles through laser. And the surface of the ceramic deposition layer is connected with the surface of the metal deposition layer through instantaneous liquid phase diffusion. The light-weight high-strength composite material is prepared by alternately depositing the metal deposition layers and the ceramic deposition layers through the laser melting deposition technology, ceramic-metal integrated structure forming is achieved, and the light-weight high-strength composite material has good rigidity and ductility while the light weight is achieved. The invention also provides a preparation method of the lightweight high-strength composite material.
本发明提供一种轻质高强复合材料，包括交替沉积的陶瓷沉积层和金属沉积层，所述金属沉积层由金属颗粒经激光熔化沉积而成，所述陶瓷沉积层由陶瓷颗粒经激光熔化沉积而成，且所述陶瓷沉积层表面与金属沉积层表面通过瞬时液相扩散连接。本发明的轻质高强复合材料，采用激光熔化沉积工艺交替沉积金属沉积层和陶瓷沉积层制备得到，实现了陶瓷‑金属一体化结构成型，在轻量化的同时具有良好的刚性和延展性。本发明还提供一种轻质高强复合材料的制备方法。
