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...

A method is disclosed of coupling and integrating natural gas recovery and separation along with chemical conversion. The method can comprise extracting at least one natural gas component. Non-limiting examples of the extracted component include ethane, propane, butanes, and pentanes. The method can also comprise contacting a natural gas stream with a catalyst under conditions that selectively convert at least one component into at least one product, such as ethylene, acetic acid, polyethylene, ...
