Abstract
Friction surfacing (FS) is a solid-state process employed for coatings that has demonstrated significant advancements in the manufacturing of aluminium matrix composites reinforced with ceramic particles. This study explores the effect of AA2017 aluminium consumable rods packed with titanium carbide (TiC) in the FS process applied to an AA6082 substrate. A subsequent post-processing friction stir process (FSP) was performed to further refine the distribution of ceramic particles. Analyses were conducted using light optical and scanning electron microscopy, X-ray diffractometer (XRD), microhardness, and pin-on-flat wear testing. The results demonstrated that the incorporation of TiC reinforcement significantly enhanced the FS deposition efficiency and rate by approximately 31%, without affecting rod consumption. Initially, the TiC particles were distributed in layers parallel to the substrate surface, but the FSP technique dispersed them throughout the aluminium matrix. In terms of mechanical properties, the reinforcement increased microhardness by 13.6% and reduced wear resistance (wear volume) by 13%. Notably, the FSP process enhanced wear resistance, reducing wear volume by 48% compared to the TiC-free coating, while also mitigating the hardness increase caused by the FS process. Additionally, XRD analysis indicated that neither FS nor FSP generated new phases, indicating no interaction between the aluminium matrix and the ceramic reinforcements.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
