Abstract (en)
[origin: WO2007082613A1] The present invention relates to an arrangement for protecting a substrate against corrosion, comprising a substrate, in particular a metallic substrate, and an electrically conductive corrosion protection layer applied to the substrate to protect the substrate against corrosion, which layer has a zinc-containing layer which has been applied to the substrate and has a passivation layer which has been applied to the zinc-containing layer for passivating the zinc-containing layer and contains many particles of hard material which have such a nature that the particles of hard material increase the coefficient of friction on a free surface of the passivation layer compared to a conversion layer without particles of hard material but leave the electrical conductivity of the passivation layer essentially unchanged. The invention further relates to a process for producing such an arrangement and a pulley.
