Abstract: A method for cleaning a surface of a component includes placing a volume of a cleaning agent onto the surface of the component. The method further includes performing a repair operation of the component either before or after placing the volume of the cleaning agent. The repair operation results in a generation of contaminant particles. Upon contact of the cleaning agent with the contaminant particles, the cleaning agent absorbs the contaminant particles by adhesion. The method further includes removing the cleaning agent from the surface of the component after the contaminant particles are absorbed by the cleaning agent.

Abstract: A method of inspecting a component comprising a cellular structure bonded to a carrier substrate to form a matrix of open-ended cells is described. The method comprises: submerging the component in an inspection liquid disposed within a pressure vessel; changing the pressure within the pressure vessel; withdrawing the component from the inspection liquid; and determining whether the cells of the component are filled with the inspection liquid. A corresponding inspection apparatus is also described.

Abstract: An arrangement for vibro-polishing one or more components, the arrangement comprising a container for containing vibro-polishing media, an agitator to agitate the vibro-polishing media relative to the container, one or more partitions extending substantially across the container so as to provide two or more sectors and, a fixture comprising at least one member which extends around one or more components for insertion into the vibro-polishing media, each member defining an opening which is sized to prevent any further fixture or partition from contacting the or each component.
