| dc.description.abstract | With the advent of contemporary buildings and large-scale workshops that require a lot of electricity, the busduct system has been chosen as the power distribution unit. Tin-plated busbars have relatively low bulk resistivity, causing higher contact resistance as high current passes by. The power loss is released as heat, increasing the joint temperature and eventually reducing current-carrying capacity. Incorporation of silver nanoparticles (AgNPs) in the Sn matrix could potentially improve the contact resistance of busduct conductors. The coating morphology, phase structure, surface roughness, and contact resistance of the Sn/AgNPs composite with magnetic stirring electroplating (MSE) and ultrasonic-assisted electroplating (USE) were compared. Also, the size and concentration of AgNPs in Sn/AgNPs via USE were studied as well. Finally, plating parameters were optimised for lab scale, and prototype samples were fabricated. The USE facilitated the co-deposition of AgNPs and formed a smooth and compact silvery-grey coating compared to that of MSE. Sn (U) has a thicker coating with less plating time than Sn (M). The average coating thickness was increased until agglomeration of white clusters was observed: Sn/10Ag3 (U) for 10 nm AgNPs addition and Sn/100Ag2 (U) for 100 nm AgNPs addition, respectively. Increasing the concentration of AgNPs, the wt% of Ag increased up to 1.77 % and 1.59 % for both types of AgNPs. The crystallise size was refined to 30.48 nm for Sn/10Ag2 (U) and 27.38 nm for Sn/100Ag2 (U). The refinement could be a combined effect of USE and AgNPs addition. Sn/10Ag2 (U) has the lowest Ra value of 1.15 nm and lowest contact resistance of 6 μΩ compared to Sn coating with 8.67 μΩ, i.e., 31 % reduction. | |
