Purpose
The corrosion resistance of copper and copper-ruthenium alloys produced by powder metallurgy (spark plasma sintering process) and exposed in 2M sulphuric acid at 45°C and 65°C was investigated using scanning electron microscopy and potentiodynamic polarisation technique.
Design/methodology/approach
The small additions of ruthenium (0.5, 1 and 2 Wt.%) to the copper resulted in improved corrosion resistance of the copper alloy by up to 90 per cent when compared to casted copper.
Findings
All the sintered copper and copper alloys proved to have increased the corrosion resistance in all the temperatures.
Originality/value
Powder metallurgy was used in achieving these improvements.
