TY - JOUR ID - TI - Impact of a Bright Nickel Interlayer on the Performance of Solar Absorber Nano Coatings Deposited by Electroplating on Copper Substrate AU - Ahmed S. Abbas AU - Khalid A. Sukkar AU - Mohammed J. Kadhim PY - 2019 VL - 37 IS - 2 Part (c) special SP - 289 EP - 295 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - Abstract: In this, work, a layer of bright nickel was deposited on the coppersubstrate using electroplating technique watts bath, before coppernanoparticles (CuNP) Evaporation via physically vapor deposition. Theimprovement of the solar absorber using CuNP and CuNP, combined withbright nickel, was found to be well than CuNP singly. Bright nickel improvedthe thermal stability of the absorber. Also the other optical propertiesabsorption, emissivity slight decrease from (93% to 87%0) in another handthermal conductivity was evaluated using hot disk analyzer with a goodimprovement obtain by CuNP( 89%) deposited on copper substrate while itdecreases with percentage18.8% in the presence of bright nickel combinedwith CuNP, other Characteristics like structure and phases of coating layersachieve using XRD, topographic was obtained using AFM and SEM
