Scalable Robotic Laser Texturing of Tilted Microanchors for Direction‐Independent Metal–Polymer Joining

Advanced Engineering Materials, EarlyView.
A robot‐assisted laser processing method is proposed that enables the formation of surface‐tilted microanchors on metal substrates to improve metal–polymer joining. Using a six‐axis robotic platform, the laser beam's incidence angle, scanning path, and interline pitch can be precisely controlled, allowing the deliberate overlap of heat‐affected zones ...
