Wear-Resistant Platinum Gold Alloy

摘要

From cellphones to satellites, industry spends millions on traditional gold alloy electrical contact coatings. While gold and other metal alloys have been an industry standard to protect metal components from wear due to metal-on-metal contact, they still experience deterioration over time. Using a novel synthesis approach, Sandia researchers developed an ultra-wear-resistant platinum gold (Pt-Au) alloy that can replace gold alloys for improved durability, longevity, and reduced costs in electronic devices.
