Abstract

In the present work copper/diamond composites, such as (Cu-10 V_f % diamond uncoated, Cu-30 V_f % diamond uncoated, Cu-10 V_f % diamond coated NiCrB and Cu-30 V_f % coated NiCrB) as heat sink materials have been fabricated using powder metallurgy and electroless techniques. The copper powder used in this study has been fabricated using electroless technique and the diamond powder was electroless coated with NiCrB film. The copper powder have been mixed with the uncoated or coated diamond particles, milled, compacted and sintered at 900°C in a hydrogen atmosphere. The corrosion behavior of the copper composite samples has been investigated in 0.6 M NaCl, 0.1 M HCl and 0.5 M NaOH solutions using potentiodynamic polarization anodic and cathodic Tafel lines and electrochemical impedance spectroscopy (EIS). Scanning electron microscopy (SEM) linking with energy dispersive X-ray spectroscopy (EDS) has been used to investigate the surface morphology and the chemical composition of the coated layer. The results of the corrosion test illustrated that the coated and uncoated Cu/diamond composites suffer from corrosion to a different extent in various electrolytes. The lowest corrosion rate in all the studied media was recorded for Cu-10 V_f % D coated NiCrB composite compared with the massive copper or uncoated composite samples.
