A gas exchange valve for an internal combustion engine may include a valve stem and a wear resistance improving functional layer. The valve stem may extend in an axial direction and may transition into a valve plate in the axial direction. The functional layer may include nickel and tungsten. The functional layer may be arranged in a coating area on an outer circumference of the valve stem and may at least partially define a sliding surface.

Gas exchange valve for an internal combustion engine

A method for manufacturing a sliding tappet of a valve train of an internal combustion engine may include the steps of: providing a main body; applying a coating at least on a contact surface of the main body configured for contacting an associated cam. The coating may include tungsten carbide and cobalt, and the coating may be applied via high velocity oxygen fuel spraying. The method may further include the step of performing a surface finishing on the coating after the coating is applied.

Method for manufacturing a sliding tappet

A piston for an internal combustion engine may include a surface in a region on a crankshaft side. The piston may include a thermally conductive coating disposed on the surface via thermal spraying.

Piston

A steel piston for an internal combustion engine may include a piston crown and a protective layer disposed on the piston crown. The protective layer may include an adhesion layer of Cr or CrN, which is present on a surface of the piston crown. The protective layer may include a functional layer, which is present on the adhesion layer. The functional layer may have at least one of (i) at least one layer (A) of CrN and (ii) at least one layer (B) of CrOn in the form of [(A)/(B)], and a may represent 1 to 100.

Steel piston for an internal combustion engine and method for its production

Disclosed is a piston () for a combustion engine, comprising hub bores () that are provided with plain bearing surfaces () and are used for accommodating a piston pin. In order to very effectively and inexpensively prevent the piston pin and the hub bores from jamming and wearing off, a self-lubricating coating () made of a thermally cured resin which contains embedded solid lubricant particles is applied directly to at least one subarea (Tb) of the plain bearing surfaces by means of rotary atomization.

Piston for an internal combustion engine and method for coating its pin bores

Disclosed is a connecting rod for a combustion engine, comprising a small connecting-rod eye that is provided with a plain bearing surface and is used for accommodating a piston pin, and a large connecting-rod eye which is provided with a plain bearing surface and embraces a crankshaft journal. In order to very effectively and inexpensively prevent the piston pin and the crankshaft journal of the connecting rod from jamming and wearing off, a self-lubricating coating made of a thermally cured resin which contains embedded solid lubricant particles is applied directly to at least one of the plain bearing surfaces by means of rotary atomization.
