Abstract
Plastic material-comprising surfaces of a substrate are coated with elemental silicon by cold gas spraying by injecting a powder containing silicon into a gas and powder with a high velocity onto the substrate surface, such that the silicon forms a firmly adherent coat on the substrate surface comprising the plastics material. Apparatuses having such silicon-coated surfaces are useful in minimizing contamination of polycrystalline silicon production, processing, packaging, and transport.
