Abstract
A tribological system for an internal combustion engine is disclosed. The tribological system includes a valve seat ring having a first contact surface and a valve having a second contact surface that can placed on the first contact surface for closing a valve opening and is arranged in a seat area of the valve. The valve in the seat area has a seat base composed of a high-nickel-content or a nickel-based material, and is coated with a nickel-based plating that comprises nickel as a main component, to form the second contact surface.

A tribological system for an internal combustion engine, comprising:
- a valve seat ring having a first contact surface,
- a valve having a second contact surface that can placed on the first contact surface for closing a valve opening and is arranged in a seat area of the valve,
- wherein the valve in the seat area has a seat base composed of a high-nickel-content or a nickel-based material, and is coated with a nickel-based plating that comprises nickel as a main component, to form the second contact surface.
A method for producing a tribological system, comprising:
- providing a valve seat ring having a first contact surface;
- providing a valve having a second contact surface arranged in a seat area of the valve that can be placed on the first contact surface for closing a valve opening;
- forming a seat base of the valve with a high nickel content a nickel-based material in the seat area to provide the second contact surface and coating the seat base with a nickel-based plating.
An internal combustion engine, comprising:
- a tribological system including:
- a valve seat ring having a first contact surface,
- a valve having a second contact surface that can placed on the first contact surface for closing a valve opening and is arranged in a seat area of the valve,
- wherein the valve in the seat area has a seat base composed of a high-nickel-content or a nickel-based material, and is coated with a nickel-based plating that comprises nickel as a main component, to form the second contact surface, and
- a charge exchange channel that can be closed or released fluidically via the tribological system so that the tribological system together with the charge exchange channel forms a charge exchange member.
