Copper Fly Ash Tungsten Composites Properties

The copper fly ash tungsten composites has gained attention in recent years due to their unique properties and potential applications. This paper, authored by Nydia Ortega, explores the mechanical and corrosion behavior of copper fly ash tungsten hybrid composites, with a focus on their properties. The composites were prepared using powder metallurgy techniques and sintering processes. The resulting microstructure, grain size, porosity, density, and hardness were analyzed. The mechanical properties, including tensile strength, compressive strength, flexural strength, fatigue strength, and creep behavior, were also examined. In addition, the wear resistance and wear behavior of the composites were evaluated, including tribology, friction, sliding wear, abrasive wear, erosive wear, and the underlying wear mechanisms. The corrosion resistance and corrosion mechanisms of the composites were also studied, including electrochemical behavior. Thermal properties such as thermal conductivity, thermal expansion coefficient, specific heat, melting temperature, and solidification behavior were also investigated. The composites' casting, machining, surface roughness, and surface morphology were analyzed using various techniques such as scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and transmission electron microscopy. Overall, this study provides valuable insights into the properties and potential applications of copper fly ash tungsten composites. The findings can be used to optimize the fabrication process, enhance the mechanical and corrosion properties, and expand the range of applications for these unique materials.
