    Abstract: A method for the production of wear-resistant edges for a keystone ring for internal combustion engines, involves forming a rectangular ring from a steel strip with a rectangular cross-section, grinding the ring edges and the outer circumferential faces to give the required profile and brushing the inner circumferential face, grinding the upper and lower ring edge to form the keystone ring, complete nitriding of the piston ring surface by a gas-nitriding process (GNS) to form a nitride layer, profiling the nitrided piston ring by grinding and lapping without machining the nitrided edges of the piston ring, stacking the piston rings on the parallel faces, coating the outer circumferential faces of the piston rings with a wearing layer, and grinding the nitrided layer of the faces in the stacked state such that at most a quarter of the total thickness of the nitrided layer is removed.

    Abstract: The present invention relates to a method for manufacturing a piston ring (10) for internal combustion engines, having the following method steps:—machining of a metal strip (20), with the result that it acquires at least one beveled face (15, 16) which represents at least one part of a ring flank of the piston ring (10) which is to be manufactured,—formation of a piston ring (10) from the metal strip (20) which has been machined in this way and the surface of which forms an inner and an outer circumferential face (11, 12) and an upper and a lower ring flank,—hardening of the surface of the piston ring (10). Furthermore, the present invention relates to a piston ring (10) for internal combustion engines, the surface of which forms an inner and an outer circumferential face (11, 12) and an upper and a lower rink flank, wherein the surface is provided with a uniformly thick hardened layer (21).

    Abstract: The cylinder running surfaces of an internal combustion engine are treated with pretreatment and coating baths by using flush-in devices (5, 11) with lances insertable into the cylinder bores (1'). The flush-in devices (5, 11) can be successively connected via manifold devices (10, 12) with reservoirs (V.sub.1 to V.sub.5 ; B.sub.1 to B.sub.3) for different bath liquors. Thus, each flush-in device (5, 11) serves for the successive introduction of different bath liquors into the cylinder bores (1').

    Abstract: A device for providing the running surfaces of the cylinders of internal combustion engines with a reinforcing coating. (e.g., a nickel dispersion layer including silicon carbide). The device is designed to hold and convey the cylinder block using a flow-trough process, and includes a baseplate (2) in which a pump (9) and the supply and discharge equipment (4-6) for the bath liquors are integrated. The device is transportable and enables the device to be used over a series of conventional treatment liquor baths.

    Abstract: The invention relates to a gear grinding machine for straight toothed or oblique toothed spur gears, in which a main slide (2) reciprocable on the machine column and an auxiliary slide (7) reciprocable on the main slide are provided for producing the rocking motion. The direction of movement of the auxiliary slide (7) is at an angle to the direction of movement of the main slide (2). The auxiliary slide (7) is linked to a slider movable in a guide slot (9). In order to employ the machine also for form grinding, the guide slot (9) is adapted to be turned parallel to the direction of movement (II) of the slide (7) and is locked in this position. Thus, a gear grinding machine is created which is suitable both for generation grinding and form grinding.
