    摘要: The present invention is concerned with a method of discriminating between, in a surface of a transition metal alloy, transition metals in different oxidation states using surface sensor molecules adapted to associate selectively with one of the transition metals. In particular, the present invention provides a method of identifying degradation in aircraft components such as turbine blades, engine casings and aerofoils. In embodiments, a surface sensor molecule comprising an oxidation state discriminating group, such as an imidazole, and a fluorescein probe is applied in aqueous solution to the surface of a service-run Ni alloy aircraft component. The sensor molecule selectively associates with transition metals in oxidation states greater than zero such that fluorescence imaging can be used to identify areas of degradation.

    摘要: A method of consolidating a powder (10) comprises the steps of filling an electrically conductive container (12) with the powder (10). Any air is evacuated out of the filled container (12), which is then sealed. The sealed container (12) is placed in a die (20) and a force is applied to consolidate the powder (10). Simultaneously an electric pulse and an ultrasonic pulse are applied to the container (12) as the powder (10) is consolidated. The electric and ultrasound pulses are applied during consolidation to disrupt the grain boundaries and assist in the fragmentation of any oxides. The container (12) is then removed from the die (20) and from the consolidated powder (10).
