The corrosion and also the erosion properties of a layer system can be improved by using deposition-hardened particles.

Layer system (1) comprises at least one substrate (4), a lower layer arranged on the substrate, preferably directly arranged on the substrate, and optionally an upper layer (7) arranged on the lower layer. The layer system has particles made of aluminum with a soft hardness, preferably a hardness of not > 50 Hv. The layer comprises aluminum containing particles, which are harder than the particles made of aluminum. The aluminum-containing particles comprise an aluminum alloy or aluminum with a c...
