摘要

采用3D打印+压力浸渗技术成功制备了陶瓷颗粒增强钢基复合材料（MMCs）/钢三维互穿网络复合材料（3DMMCs/steel）

其中MMCs区呈相连的球状

与纯基体区在空间呈三维互穿结构

MMCs区中均匀分布着ZrO2增韧Al2O3颗粒（ZTAp）

MMCs区基体和纯基体区都为40Cr钢。研究了该复合材料的微观组织特征和冲击磨料磨损性能

并与常规增强颗粒均匀分散的ZTAp/40Cr复合材料进行了对比。三维互穿网络复合材料结构完整

界面结合良好

其冲击磨料磨损性能高于常规复合材料

磨损率比常规复合材料降低了31.24%。

Abstract

The composites of MMCs and steel with three dimensional interpenetrating network structure（3D-MMCs/steel）were fabricated by 3Dprinting combining with pressure infiltration method.Zirconiatoughened alumina（ZTA）particles are taken as the reinforcement of MMCs

and the matrix of the MMCs and the steel are 40 Cr steel.The MMCs area and the steel area in the composite are continuously interpenetrated in the three dimensional network.The microstructure and impact abrasive wear behavior of the composite were analyzed by comparing with those of the ZTAp/40 Cr composites.The results show that the wear volume loss of 3D-MMC/steel composite is reduced by 31.24%

and the composites prepared have complete structure and satisfied bonding interface.
