The invention provides for a cylinder bore coating system that includes at least one cylinder bore configured to receive an axially movable piston. The at least one cylinder bore has a recessed area having an axial length and a radial depth. A first coating layer is arranged within at least the recessed area. A second coating layer covers the first coating layer and a portion of the at least one cylinder bore axially spaced from the recessed area.

Workpiece having a cut-out for receiving a piston

A component stack is coated such that, during a first coating pass, a first angle (&#x3b1;) is formed between the first stack opening surface and the coating beam and, during a second coating pass, a second angle (&#x3b2;) is formed between the first stack opening surface and the coating beam, wherein the first angle (&#x3b1;) and the second angle (&#x3b2;) are formed in opposite directions relative to the first stack opening surface.

Thermal coating of a component stack and of component stacks

The invention relates to a bearing part as well as to a spray method for manufacturing a layer system on a bearing part, such as, in particular, a connecting rod eye of a connecting rod for a reciprocating piston combustion engine, with a layer system containing at least tin being provided on a surface of the bearing part. In accordance with the invention, an outer, thermally sprayed, top layer of the layer system is composed only of tin with the exception of contaminants.

Bearing part and thermal spray method

Spray material for thermally coating a substrate, a thermal spray layer, and a cylinder for a reciprocating piston combustion engine coated with the thermal spray layer. The spray material includes a solid lubricant of ZnO. A volume fraction of ZnO in the spray material lies in a range from 0.1% to 15% of the volume of the spray material.
