The application of Thin Layer Activation (TLA) technique to Al2O3 components

The small amount of wear generated by hip components hampers its precise assessment by gravimetric measurements. Thus, the possibility of applying the Thin Layer Activation (TLA) technique to ceramic components was taken into account during the last months of the project. The obtained results demonstrate that the activation of alumina is possible. The employment of TLA allows a highly sensitive measurement of wear, with a resolution in the sub-nanogram range, and it represents a mean to investigate the dissolution of material due to a liquid environment. Future investigations on this technique will provide quantitative data about the wear of ceramic hip components.
