  • Pre-diffused Al—Si coatings for use in rapid induction heating of press-hardened steel
    Patent number: 9677145
    Abstract: A press-hardened steel component and a method of producing the same. In one form, a workpiece that will be formed into the component includes a coating that is pre-diffused with metal from the workpiece substrate. Examples of such protective coatings may include aluminum-based coatings, as well as from aluminum and silicon combinations. The pre-diffusion of the workpiece permits it to be subjected to the high heating rate of a subsequent press hardening operation without causing localized melting or vaporization of the protective coating.
    Type: Grant

  • Sealed edge joint between two metal panels
    Patent number: 6368008
    Abstract: A vehicle closure panel assembly having an outer panel and an inner panel. The outer panel has a flange along one edge which is folded over a flange of the inner panel. A metal coating provides a seal between the edge of the flange of the outer panel and the flange of the inner panel. The coating is made of metal and is sprayed on. The metal coating provides a mechanical and metallurgical bond and may offer sacrificial protection against corrosion and instantaneous or immediate bonding.
