Influence of laser surface structuring of steel sheets on the mechanical properties of electrodeposited ZnNi coatings

The influence of laser surface structuring on the formation and internal strength electrodeposited ZnNi coatings steel sheets was investigated. Surface by extended direct interference patterning (xDLIP) used to modify cohesive in layer. An SEM analysis crystal structures shows perpendicular nucleation during layer areas crosslinked crystalline structures, which results an interlocking within interlocked structure leads increase layer, observed roller peel tests according DIN 1464 for adhesively bonded joints.
