Method for producing a layer by means of cold spraying and use of such a layer

A method generates an abrasive wear-resistant layer on a substrate. The layer is formed of particles of a ductile material, in particular Zn, wherein the parameters of the cold spraying process are set such that a comparatively loose laminate having pores is formed by the spray particles. The lamina...

Beschreibung
Zusammenfassung:	A method generates an abrasive wear-resistant layer on a substrate. The layer is formed of particles of a ductile material, in particular Zn, wherein the parameters of the cold spraying process are set such that a comparatively loose laminate having pores is formed by the spray particles. The laminate advantageously and surprisingly exhibits high resistance to abrasive wear (for example by a particle) because the layer can avoid the attack by the particle by plastic deformation and closure of the pores, whereby abrasive removal of the layer is advantageously low. The cold gas-sprayed layer is used as a protective layer against abrasive wear.
