  • Contact element and a contact arrangement
    Patent number: 8487201
    Abstract: A contact element for making an electric contact to a contact member for enabling an electric current to flow between the contact element and the contact member. The contact element includes a body having at least one contact surface thereof coated with a contact layer to be applied against the contact member. The contact layer includes a nanocomposite film having a matrix and crystallites of nano-size embedded therein. Portions of the matrix separating adjacent the crystallites of the nanocomposite film have a thickness providing the matrix and hence the film with an electrical conductivity determined by a substantially two-dimensional character of the matrix.
    Type: Grant
    Filed: May 14, 2008
    Date of Patent: July 16, 2013
    Assignees: ABB Research Ltd., Impact Coatings AB

  • Contact element and a contact arrangement
    Patent number: 7709759
    Abstract: A contact element for making an electric contact to a contact member for enabling an electric current to flow between the contact element and the contact member includes a body having at least one contact surface thereof coated with a contact layer to be applied against the contact member. The contact layer includes a nanocomposite film having a matrix of amorphous carbon and crystallites of nano-size, i.e. with dimensions in the range of 1-100 nm, of at least one metal carbide embedded therein.
