摘要

摘要采用真空烧结法制备了梯度分布的VCp-ZTAp/Fe45复合材料，并进行了三体磨料磨损实验，研究了其耐磨性能。采用有限元方法和实验研究了VCp-ZTAp/Fe45复合铸造，并对Fe45基体与35SiMnCrMoNi钢的结合进行了全面的研究。结果表明，在真空烧结过程中，VCp-ZTAp/Fe45复合材料基体中原位形成了VCp。VCp-ZTAp/Fe45复合材料的抗磨性能约为Hardox450和NM450的7倍，约为30SiMn的8倍。VCp-ZTAp/Fe45的Fe45基体与35SiMnCrMoNi钢之间形成了牢固的冶金结合，在复合铸造过程中，结合区的厚度约为80μm。

Gradient-distributed ZTAp-VCp/Fe45 as new anti-wear composite material and its bonding properties during composite casting

Abstract In this article, gradient-distributed VCp-ZTAp/Fe45 composites were prepared by vacuum sintering, and three-body abrasive wear experiments were carried out to investigate its anti-wear performance. The composite casting of VCp-ZTAp/Fe45 was investigated by using the finite element method and experiments, and the bonding between the Fe45 substrate and 35SiMnCrMoNi steel was fully investigated. Results show the in situ formation of VCp in the VCp-ZTAp/Fe45 composite matrix during vacuum sintering. The anti-wear property of the VCp-ZTAp/Fe45 composite is ca. 7 times that of Hardox450 and NM450 and ca. 8 times of 30SiMn. There forms a solid metallurgical bonding between the Fe45 matrix of VCp-ZTAp/Fe45 and 35SiMnCrMoNi steel, with a ca. 80 μm thickness of the bonding area during the composite casting.

期刊介绍： Science and Engineering of Composite Materials is a quarterly publication which provides a forum for discussion of all aspects related to the structure and performance under simulated and actual service conditions of composites. The publication covers a variety of subjects, such as macro and micro and nano structure of materials, their mechanics and nanomechanics, the interphase, physical and chemical aging, fatigue, environmental interactions, and process modeling. The interdisciplinary character of the subject as well as the possible development and use of composites for novel and specific applications receives special attention.
