Abstract

Boride ceramics are potential reinforcements for copper matrix composites due to their excellent mechanical and electrical properties. The synergistic effect of dual-phase and dual-scale boride can enhance both the wear resistance and electrical conductivity of composites. In this paper, MoB₂-ZrB₂/Cu hybrid composites with varying boride contents were prepared using spark plasma sintering. The microstructure and phase composition of these composites were characterized. The hardness, compressive strength, and tribological properties were measured. The results indicate that ZrB₂ microparticles and MoB₂ nanoparticles were dispersed within the Cu matrix. Additionally, the composites exhibited desirable interfacial bonding between the boride particles and the Cu matrix. The “hybrid effect” of the dual-phase borides enhanced the electrical conductivity, mechanical, and tribological properties of the MoB₂-ZrB₂/Cu composites. The wear mechanism of the MoB₂-ZrB₂/Cu composites involved a combination of abrasive wear, oxidation wear, and fatigue wear.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
