Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for forming a ductile, plastically deformable abrasion-resistant layer on a substrate, comprising: forming the abrasion-resistant layer by accelerating particles having an average particle size of 1-10 μm by cold spraying the particles towards the substrate at a speed to cause the particles to impinge and adhere to the substrate and such that the formed abrasion-resistant layer is porous, wherein the cold sprayed particles are formed from a…
