| Abstract: | In this study, the in vitro degradation behaviour of a friction stir processed AZ31 magnesium alloy was investigated. Electrochemical
experiments in simulated body fluid suggest that friction stir processing marginally enhances the degradation resistance of
the alloy, which could be attributed to the dissolution of secondary phase particles. Homogenisation of the microstructure
reduces galvanic corrosion. It is envisaged that the beneficial effect would be more pronounced for magnesium alloys which
contain high volume fraction of galvanic corrosion inducing secondary phase particles. |
