摘要

Producing at least partially coated cylinder bore of a crankcase of a reciprocating engine, comprises: at least localized heating of a surface layer on a blank of the crankcase, in which the outer layer represents a predetermined thickness of the cylinder bore, heating by using at least one heat source with a predetermined heat input, varying at least one material property of the outer layer; conditioning the surface of the cylinder liner, according to predetermined criteria change of at least one surface parameter; and coating the cylinder bore.
