A process for enhancing the mounting surface of a hard surface comprises rotating a hard material having a planer mounting surface about an axis perpendicular to its surface and intercepting said surface with a laser beam, directed along an axis which is at an angle to the surface's rotating axis. The, laser beam cuts a void through the rotating mounting surface and into the material, creating an undercut for enhanced mechanical bonding properties. By repositioning the relative positions of the laser beam and rotating surface a, plurality of different undercut voids can be formed. Preferably the laser beam can, be pulsed and synchronized with the speed of rotation of the surface for …
