METHOD FOR FORMING THREE-DIMENSIONAL ANCHORING STRUCTURES ON A SURFACE

摘要

A method including: forming a melt pool (16) on a solid surface (12); applying an energy beam (10) to melt solid material (18) adjacent the melt pool; controlling the energy beam such that the melting of the solid material adjacent the melt pool creates a wave front (22) in the melt pool effective to form a protrusion (20) of material upon solidification.
