20.500.12556/RUL-146706 Wear behaviour of a Cu-Ni-Sn hybrid composite reinforced with B4C prepared by powder metallurgy technique Obrabne lastnosti hibridnega kompozita Cu-Ni-Sn, ojačenega z B4C in pripravljenega po postopkih metalurgije prahov Cu matrix composites benefit from the high electrical and thermal conductivities of Cu and the mechanical wear/erosion resistance of hard reinforcement. In this study, an attempt has been made to determine the effect of the addition of reinforcement B4C in Cu-Ni-Sn. The B4C is reinforced to form a hybrid Cu matrix composite with powder metallurgy technique. The hybrid composites are obtained by milling, blending, and compacting the powders to obtain a fine grain-sized particle without aggregation. The grain size and particle nature were characterized using scanning electron microscope (SEM) and X-ray diffraction (XRD) techniques, respectively. The microstructure, density, hardness, and wear rate of the composites were studied. The pin-on-disc method is equipped to study the wear behaviour and coefficient of friction. The sintered density of the prepared Cu-15%Ni is 98.25 %, Cu-8%Sn is 98.20 %, Cu-15%Ni-8%Sn is 98.10 % and Cu-15%Ni-8%Sn-2%B4C is 95.26 % and lower specific wear rate has been recorded for Cu-15Ni-8Sn-2B4C 121×10-6 mm3/(Nm) and the addition of reinforcement B4C in Cu-Ni-Sn displays remarkable changes in wear rate and friction coefficient. powder metallurgy copper wear characterization density composites metalurgija prahov baker obraba karakterizacija gostota hibridni kompoziti vrstični elektronski mikroskop rentgenska difrakcija true false true Angleški jezik Slovenski jezik Članek v reviji 2023-06-08 13:51:16 2023-06-08 13:51:20 2023-06-09 03:42:27 0000-00-00 00:00:00 2023 0 0 Str. 275-283 no. 5/6 Vol. 69 May/Jun. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 669:539.43 0039-2480 10.5545/sv-jme.2022.423 155014659 Allasi...-Wear_behaviour_of_a_Cu-Ni-Sn_hybrid_composite_reinforced_with_B4C_prepared_by_powder_metallurgy_technique.pdf Allasi...-Wear_behaviour_of_a_Cu-Ni-Sn_hybrid_composite_reinforced_with_B4C_prepared_by_powder_metallurgy_technique.pdf 1 1D3AC429BCDCA4A9F4D8C586D55C8673 281f8a566157ccd99ac80fd3b043f9ae387b46097886f2e38c81707ecd6e6c11 92550e11-05f2-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169973 https://www.sv-jme.eu/sl/article/wear-behavior-of-b4c-reinforced-with-cu-ni-sn-hybrid-composite-prepared-by-powder-metallurgy-technique/ 1 813cb569-05f2-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169972 Fakulteta za strojništvo Strojniški vestnik 0 0 0
