Evaluation of mechanical and wear properties of AA6063/(Si₃N₄)_6%–12% /(CuN₂O₆)_2%–4% composite via PM route and optimization through robust design technique

Abstract The study is to investigate the physical, mechanical, and tribological properties of Al6063 alloy reinforced by Silicon Nitride (Si 3 N 4 ) & compound Copper Nitrate (CuN 2 O 6 processed via Powder Metallurgy (PM) Techniques. Incorporation reinforcement in matrix material ranged from 12% Si a 6-step interval, 6%CuN two-step interval. characterizations were made on PM produced specimens using OM, EDS, XRD hardness. particles distributed uniformly attributed homogeneous mixer reinforcements. tests carried out accordance with ASTM Standards its composites. test findings show that as reinforcing percentage ceramic inorganic increased, such hardness density rise monolithically considerably. dispersion CuN AA6061 was ensured x-ray diffraction patterns. In comparison base alloy, AA6063/12%Si /6% improved 88% due mismatch thermal expansion between Al causes huge internal stress, causing aluminium deform plastically lodge smaller volume particles. dry sliding wear tribometer pin-on-disc arrangement, composite has higher resistance. Taguchi design experiments used solution containing parameters employing an orthogonal array, signal-to-noise ratio, analysis variance. weight /CuN relationship wt% applied load had highest impact resistance, accounted for 31.66%.
