Method of cleaning a plasma coating torch utilizing at least one nozzle mounted so as to be directed at the plasma coating torch in order to subject an external surface of the plasma coating torch to a cleaning agent that removes spray material particles which have adhered to the external surface of the plasma coating torch during coating with the plasma coating torch, and such that the cleaning agent exiting the at least one nozzle and being directed toward the external surface and directly changing to a gaseous state from either a solid state or a liquid state.

The invention relates to a zinc-free spray powder for thermally coating a substrate, in particular for thermally coating a bearing part of a bearing apparatus, which spray powder has the following composition except for unavoidable contaminants: tin=5% to 30% weight percent; aluminum=0.1% to 5% weight percent; iron=at most 1% weight percent, and copper=difference to 100% weight percent. The invention furthermore relates to a layer system applied via thermal spraying, a work piece, particularly a connecting rod, as well as a spray method for manufacturing a spray layer.

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.

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.
