Abstract

The effects of TiC and Cr₇C₃ contents on the mechanical and wear properties of carbide particles reinforced iron composites are investigated in the present work. Firstly, the Cr₇C₃–TiC–Fe composites designed from CALculation of PHAse Diagrams (CALPHAD) method were fabricated by the spark plasma sintering (SPS) process. Subsequently, their microstructure, hardness, and wear property were measured by using the scanning electron microscopy (SEM), microhardness tester, and three-body abrasive wear tester, respectively. Finally, the relationship between carbide contents and mechanical or wear property was discussed. The results show that Cr₇C₃–TiC–Fe composites with excellent wear property can be used as attractive candidates of wear-resistant materials.

放电等离子烧结TiC-Cr7C3-Fe复合材料的显微组织及磨粒磨损性能

研究了TiC和Cr7C3含量对碳化物颗粒增强铁复合材料力学性能和磨损性能的影响。首先，采用火花等离子烧结（SPS）工艺制备了相图计算法（CALPHAD）设计的Cr7C3-TiC-Fe复合材料。采用扫描电镜（SEM）、显微硬度计和三体磨料磨损试验机分别对其显微组织、硬度和磨损性能进行了测定。最后，讨论了碳化物含量与合金力学性能和磨损性能的关系。结果表明，Cr7C3-TiC-Fe复合材料具有优异的耐磨性能，可作为有吸引力的耐磨材料候选材料。

期刊介绍： The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
