Abstract (en)
[origin: WO2009152831A1] The invention relates to the production of components for gas injection systems and/or internal combustion engines, said components having low fault liability and a long service life. To this end, the components, which come into contact with liquefied gas or natural gas, are coated at least in the regions which come into contact with gas. The coating is characterised in by a high resistance to wear, high corrosion resistance, favourable friction properties, and a good anti-adhesive action.
