Abstract
Cu-Co alloys with different manganese contents, were synthetized using the induction melting technique. Thermal treatments were applied to the resultant alloys, obtaining minimum superficial porosity. Scanning electron microscopy reveals a copper rich matrix and a secondary phase constituted of Mn-Co with precipitates mainly thorough the grain boundaries. Hardness evaluation shows average values for samples thermal treated of 138 HV which represent 12% lower than untreated samples, produced by the homogenization of the microstructure. Tribological analyses indicated that samples thermal treated have reached a noticeable increment in their wear resistance under an oxidative wear mechanism which make it as a promissory alloy for aeronautical applications.
