A method for roughening and thermally coating a surface, in particular a cylinder running surface of an internal combustion engine, the roughening being the preparation of the surface for the thermal coating of the surface with a coating. The method is characterized in that different roughening profiles are introduced into the surface during the roughening and the coating has different properties distributed over the surface. This allows the coating or spraying process during the later thermal coating to be carried out with substantially constant spraying parameters. The different properties of the coating, such as hardness, porosity, machinability, chemical composition, oxidation and adhesion, are then obtained just on the basis of the differently roughened surface.

A system for cold gas dynamic spraying of particulate material has a de Laval nozzle and two or more radial particle inlets located between the throat and the outlet of the nozzle, the two or more particle inlets arranged symmetrically around a linear flow path of the nozzle. Blocking of the inlets is reduced by controlling pressure of particle carrier gas to provide a stable particulate material injection pressure before and during introduction of working gas into the nozzle, and/or by clearing the particle inlets of residual particles after a spraying process. Such a system and associated method combines benefits of both downstream and upstream cold gas spray systems. Further, a nozzle for spraying particulate material having a cross-sectional shape that is narrower in a middle section compared to edge sections provides coatings with superior cross-sectional profiles.

The invention relates to a method for forming at least one structure on a substrate. By means of a low-temperature plasma jet, powder, of which the structure shall be constructed, is applied to a surface of the substrate. By means of at least one laser beam, heat is input into the substrate and/or the powder within a laser incidence region on the substrate. The heat input delays solidification of the powder particles, which are partly or fully melted in the plasma jet, on the substrate and thereby enables the formation of good adhesion between the applied powder, and thus the structure constructed thereof, and the substrate. The invention further relates to an apparatus for performing the method.
