Mathematical Fuzzy Modeling to Estimate Erosion Wear Rate of a Novel Metal Matrix Composite Produced by Powder Metallurgy Method

The field of materials is currently undergoing extensive research to identify novel materials possessing characteristics such as low weight, high strength, and exceptional mechanical properties. This pursuit an investigation into metal matrix-composites those are both lighter and stronger. The study revolves around the development of an innovative aluminium composite material characterized by notable density, favourable machinability, low corrosion susceptibility, high strength, light weight, and cost-effectiveness. In this research an aluminium metal matrix composite of aluminium-0.5, silicon-0.5, magnesium-2.5, copper-15, silicon carbide-1, 3, 5, 7, 10, 12 and 15 was developed by metallurgical powder method and subjected to the study of erosion wear properties. The investigation involved conducting solid-particle erosion tests on prepared samples. A total of thirty five tests were executed, considering four key process parameters: the percentage of silicon carbide, stand-off distance, impact velocity, and impact angle. The experimental findings revealed that the erosion rate exhibited minimum with an increasing of impact angle, irrespective of the impact-velocity. Additionally, at higher impact velocities, the erosion rate showed an increase, while it decreased with an increasing stand-off distance. Using different erosion test input parameters in the fuzzy model, the fuzzy results and experimental data showed a percentage deviation not exceeding 2.91 percent.
