A ceramic armoring is provided, comprising a first ceramic layer which has a plurality of segments that are functionally separated by crack stoppers, wherein the crack stoppers serve to prevent cracks propagating from one segment to another segment, at least one second ceramic layer which has a plurality of segments that are functionally separated by crack stoppers, and at least one bonding layer by means of which the first ceramic layer and the second ceramic layer are joined together, wherein the segments of the first ceramic layer are offset with respect to the segments of the second ceramic layer.

Ceramic armoring and method for the production of ceramic armoring

To provide a universally usable free-piston device with electric linear drive, comprising at least one piston receptacle with at least one piston device arranged for linear displacement in the piston receptacle, the piston device comprising a traveller device, and a stator device being arranged on the piston receptacle, and the at least one piston device being drivable under the action of a medium which expands in an expansion space, it is proposed that the piston stroke be variably adjustable via the linear drive such that the dead centers of the displacement of the piston device are definable.
