Özet
The current work related to investigate wear and corrosion properties for addition three weight% of copper to Ti-18Nb alloy using powder metallurgy technique including (5, 7 and 9 wt%). The percent of 7% gave the lowest wear rate for base alloy (Ti-18Nb) because of formation a hard Ti2Cu phase, with different properties for the corrosion behavior because of the variation in produced cathodic and anodic areas in tested medium (simulated body fluid) and then increasing the micro-galvanic cells over the alloy's surface, adding 9% Cu gave polarization resistance equal to (448.46 k ohm cm(2)) that was higher than resistance of base alloy and alloy with 5 and 7% Cu. Atomic force microscopy was used to analysis the surface topography with measuring the roughness of surface; also 7% of Cu gave the highest surface roughness (20.06 nm) compared with other percents due to the formed hard phase.
