Abstract
A method for producing an internal combustion engine, includes the steps of providing a cylinder comprising a cylinder wall, wherein a surface of the cylinder wall has a structure which is designed and formed such that it can be penetrated by a coating; generating at least one barrier region by way of at least regional machining of the structure such that the coating cannot penetrate into the structure; and applying a coating to the cylinder wall, which coating does not penetrate into the structure in the at least one barrier region.
Claims15
A method for producing an internal combustion engine, comprising:
- providing a cylinder comprising a cylinder wall, wherein a surface of the cylinder wall has a structure which is designed and formed so as to be penetrable by a coating;
- generating at least one barrier region by way of at least regional machining of the structure such that the coating cannot penetrate into the structure in the at least one barrier region;
- applying the coating to the cylinder wall, which the coating does not penetrate into the structure in the at least one barrier region.
A cylinder for an internal combustion machine, comprising:
- a cylinder wall;
- a coating provided on the cylinder wall, wherein
- the coating together with the cylinder wall form at least one cavity disposed between the coating and the cylinder wall;
- the cavities are produced by:
- providing a cylinder comprising the cylinder wall, wherein
- a surface of the cylinder wall has a structure which is penetrable by the coating;
- generating at least one barrier region by way of at least regional machining of the structure such that the coating cannot penetrate into the structure in the at least one barrier region;
- and
- applying the coating to the cylinder wall, which coating does not penetrate into the structure in the at least one barrier region.
