  The issue is that, from my understanding, it needs to be in a low/no oxygen environment to prevent the oxidized layer that forms and blocks the metal from fusing. I’ve heard from interviews with astronauts that they can re-fuse chunks of metal in space by just pushing them back together.

    “Autonomous healing of fatigue cracks via cold welding”

    That’s the literal name of the paper. I’m quite over this story getting pumped around the internet. This is not news. This is not novel.

    Yeah and preventing that from happening in space is rather complex task. Especially on parts that grind against each other causing the existing oxidized layer to wear off.
