Latest Patents

One of Ji Heon Jun's latest patents is focused on a fastener joint and associated method for avoiding corrosion of dissimilar material fastener joints. This invention involves a fastener designed to join dissimilar materials, which is manufactured to have an external surface that forms an electrically insulating oxide layer when subjected to oxidation. The process includes a pre-oxidation step to grow the desired oxide layer in situ on the fastener's external surface before its use. The invention also details a dissimilar material joint where the pre-oxidized fastener is utilized to mechanically join materials, with the oxide layer providing electrical insulation from at least one of the materials. The fastener may be a rivet used in friction self-piercing riveting (F-SPR) and can be fabricated from an alloy capable of forming AlO or CrO through thermal oxidation. Additionally, the fastener may be pre-coated with Al or Cr, which serves as a seed layer for oxide formation.
