Investigations on mechanism of the friction-assisted selective area electrodeposition and its application in worn surface repairing.

Summary: Imagine your favorite machine breaks down because a tiny metal part gets worn out. Instead of throwing the whole machine away, what if we could just "re-grow" the missing metal? Scientists are testing a cool new method called friction-assisted electrodeposition (FAED). They use electricity and rubbing to perfectly patch up worn spots with a mix of iron, cobalt, and nickel. This helps parts last much longer, saves money, and is great for the environment because it reduces industrial waste!
