Abstract

The Cu98Ge2 alloy was annealed at 500 °C, 600 °C and 700 °C for 2 hours and characterized by x-ray diffractmeter, scanning electron microscope, digital Vickers micro-hardness tester and Gamry Potentiostat/Galvanostat with a Gamry framework system based on ESA 300.  X-ray and scanning electron microscope analysis show a significant change on microstructural of Cu98Mn2 alloy after annealing at different temperature for 2 hours.  Lattice microstrain of Cu98Mn2 alloy varied after annealed at different temperature for two hours.  Vickers hardness and corrosion rate values of Cu98Mn2 alloy increased after annealing at different temperature for 2 hours.  Corrosion current of Cu98Mn2 alloy decreased after annealing at 500 °C and 600 °C but it increased at 700 °C for 2 hours.  The best annealing temperature for Cu98Mn2 alloy is 500 °C for 2 hours.
