Process of forming a composite coating on a substrate

This invention describes a way to put a super-strong, wear-resistant coating on metal parts like steel or aluminum. It works by melting a tiny bit of the metal surface and, at the same time, feeding a special reinforced metal wire into that molten spot. The two molten materials mix and react to form the new protective layer, with the heat source precisely controlled by a robot or by scanning a beam.

Why it matters: Filed before modern industrial robotics and real-time adaptive control systems were widely available or as precise. Today's advanced lasers, plasma systems, and sophisticated robotic platforms make the precise thermal processing and adaptive control described in the claims much more achievable and cost-effective.
