Abstract

ABSTRACT. In this work, the Copper composites Cu-x wt. % B4C (x = 0, 5, 10, 15, 20) were fabricated for the metallurgical and mechanical property evaluation as per ASTM standards. The metallurgical characterization tests on the samples include x-ray diffraction, optical microscopy, and scanning electron microscopy with EDX. Further, pin-on-disc apparatus was used to investigate the tribological behavior of composite specimens. An SEM micrograph of the worn surface and wear debris, along with the Gwyddion software, has been used to discuss the wear mechanisms in detail. The Artificial Neural Networks (ANN) classifier model is also constructed to describe the wear behavior in more detail. The experimental results inferred that the addition of Boron carbide particles has enhanced the Copper's corrosion resistance in a 1 M HCl electrolyte solution from 30.34% to 74.2%, 75.08%, and 83.29% with B and C ions. Also, it significantly enhance the mechanical and tribological characteristics considerably. KEY WORDS: Powder metallurgy, Cu-B4C, Gwyddion, Wear, Artificial Neural Network Bull. Chem. Soc.

化学成分对碳化硼增强铜复合材料电化学和磨损行为的影响

摘要。在这项工作中，根据ASTM标准，制备了铜复合材料Cu-xwt.%B4C（x=0，5，10，15，20），用于冶金和机械性能评估。样品的冶金表征测试包括x射线衍射、光学显微镜和EDX扫描电子显微镜。此外，使用销-盘装置研究了复合材料试样的摩擦学行为。磨损表面和磨损碎屑的SEM显微照片以及Gwydion软件已被用于详细讨论磨损机制。还构建了人工神经网络（ANN）分类器模型来更详细地描述磨损行为。实验结果表明，碳化硼颗粒的加入使铜在1M HCl电解液中对B和C离子的耐腐蚀性从30.34%提高到74.2%、75.08%和83.29%。此外，它显著提高了机械和摩擦学特性。关键词：粉末冶金，Cu-B4C，Gwydion，磨损，人工神经网络公牛。化学。Soc.Ethiop。2023,37（4），959-972.DOI:https://dx.doi.org/10.4314/bcse.v37i4.12
