Abstract: A coating for a tribologically heavily loaded component, wherein the coating is in the form of a ceramic coating made of an organic-inorganic prepolymer which is pyrolyzed after being applied to the component.

Abstract: A method of producing a cooling channel piston for an internal combustion engine having a cooling channel in its piston crown, wherein a piston lower section with piston bosses, piston pin bores and piston skirts attach to the piston crown, wherein a piston blank is first produced with a circumferential collar radially projecting in the area of the piston crown, wherein the collar is then formed over, wherein, a seating area for the collar is formed in a transition zone between the piston crown and the piston lower section and the collar is formed over in such a way until its outer radially circumferential edge comes very close to or butts completely against the seating area to form a closed cooling channel.

Abstract: Manufacturing process for a cooling channel piston with formable shoulder Process for manufacturing a cooling channel piston which has a cooling channel approximately in the area behind the ring belt, where a piston blank is shaped at least partially by forging, where in accordance with the invention it is envisaged that a circumferential shoulder is formed in the area of the heat dam also by forging, a recess is introduced behind the shoulder and the shoulder is subsequently reshaped by deformation in such a way that the recess is closed by the shoulder to form a cooling channel.

Abstract: The invention relates to a process for manufacturing a single-piece cooling channel piston, where a piston blank produced by forging is furnished with a circumferential ring-shaped recess between the piston skirts and the piston crown and with an open-bottomed cooling channel in the area of a piston ring belt, where to increase the surface guidance area of the piston skirts it is envisioned that a component extending this piston ring belt is welded on below the piston ring belt.

Abstract: A molding body for the production of a cavity in a metal casting such as a piston of an internal combustion engine, the molding body being composed of calcium silicate fibers held together in a solid form by a soluble binding agent.

Abstract: The invention relates to a process for producing a cooling channel piston, in which the overall height is reduced in that the annular recess has a lower height than the height of the tool used for producing the cooling channel, and the production of the cooling channels starts parallel to the piston boss face, in which the axial height of the annular recess (8) is smaller than the axial height of the cooling channel (13).

Abstract: A light metal piston for internal combustion engines which includes a bearing bushing comprising a shell wrapped from a rolled strip or band shaped metal material. The shell has a butt joint which is closed in a pressed-in state, with a preferred orientation of the metallurgical grain areas being formed in the circumferential direction of the shell.
