Latest Patents

One of Yong Chae Lim's latest patents is titled "Fastener joint and associated method for avoiding corrosion of dissimilar material fastener joints." This invention focuses on a fastener designed for joining dissimilar materials. The fastener is manufactured to have an external surface that forms an electrically insulating oxide layer when subjected to oxidation. Prior to use, the fastener undergoes a pre-oxidation process to grow the desired oxide layer in situ on its external surface. This innovation allows for a dissimilar material joint where the pre-oxidized fastener mechanically joins materials while the oxide layer electrically insulates the fastener 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 by thermal oxidation. Additionally, the fastener may be pre-coated with Al or Cr, which serves as a seed layer for forming AlO or CrO.
