POWDER METALLURGICAL FABRICATION OF CO REINFORCED CUNISI MATRIX COMPOSITES: MICROSTRUCTURAL AND CORROSION CHARACTERIZATION

Copper (Cu) and its alloys are used in various composite materials in different industries such as automotive, aviation, biomedical, and space, due to their superior properties such as high corrosion resistance, heat resistance, electrical properties, strength, and toughness. However, some difficulties are encountered in the use of Cu and its alloys in industry in terms of their mechanical properties. For this reason, it is observed that studies aimed at increasing the mechanical properties of CuNiSi alloy are limited in the literature. In this study, cobalt particles were added into the CuNiSi matrix at different rates and mixed homogeneously with a three-dimensional turbula for 3 hours. The results of experimental studies reveal that CuNiSi matrix composite materials can be successfully produced in terms of microstructure and mechanical properties. During the production phase of the samples, the powder metallurgy method was used by mixing Cu, Ni, Si, and Co powders in different chemical composition ratios. In this production process, argon atmosphere was used to prevent oxidation of the samples and for the synthesis process during sintering. After production, Scanning Electron Microscopy (SEM) analyses were applied for the characterization of the samples. Additionally, corrosion tests were carried out for corrosive characterization of the produced samples. As a result of the analyses, it was determined that the high melting temperature, high strength, and high mechanical properties of Co particles increased the microstructure and mechanical properties of the CuNiSi alloy. These findings show that CuNiSi matrix composite materials can be made more effective and durable in industrial applications by improving them with the addition of Co. The results of the potentiodynamic polarization experiments are presented and contain important data on the corrosion behavior of the samples with different cobalt reinforcement amounts. There is an increase in porosity values with the increase in the amount of cobalt reinforcement in the samples.
