Oligodynamic Cu-Zn composite fabricated by powder metallurgy method

The emergence of antimicrobial resistance is becoming a serious threat for the effective prevention from infection caused by bacteria. Materials such as silver, Copper, Zinc, ZnO, CuO, carbon and their composites have recently received much attention. due to their oligodynamic properties. This work investigates the properties of Cu/Zn composite fabricated by powder metallurgy method, as oligodynamic materials. By varying the concentration of Zinc in composite, the effect on the samples have been elaborated using X-ray diffractometer (XRD), Optical Microscope and antibacterial activity test. XRD diffractogram shows structure and all unit cell parameter of the samples. The different iunit cell parameter is likely due to pressure during samples preparation. The sample exhibit different surface morphology, before and after antibacterial activity test. All samples clearly show different antibacterial activity (paper)
