Abstract

Mechanical interlocking is a joining technique capable of mechanically bonding two dissimilar materials by means of protrusions on the component surfaces, as an alternative or complement to mechanical fasteners or adhesives. Proper adhesion between materials, and joint retention mainly depend on the shape and strength of the interlocking structures. In this respect, additive manufacturing is used to optimize the interlocking design and performance. The intent of this research is to evaluate the effectiveness of laser powder bed fusion and post-processing treatments on AlSi10Mg interlocking structures. The geometry, microstructure and density of the structures are investigated utilizing metallographic and tomographic techniques.
