  • Steel substrate with metal coatings for the reinforcement of vulcanizable elastomers
    Patent number: 4978586
    Abstract: The invention relates to a steel substrate with metal coatings for the reinforcement of vulcanizable elastomers, as well as a method for the continuous manufacture of a thus coated substrate and elastomer objects reinforced with said substrate.The substrate is provided with a first coating and a second coating at least covering part of the first one and a bonding layer being present between the two said coatings. The second coating comprises e.g. cobalt that can be applied by plasma sputtering. The coating combination can be easily adapted to the specific elastomer compositions and the reinforcement requirements aimed at.
