Optimization on hardness and internal stress of micro-electroformed NiCo/nano-Al2O3composites with the constraint of low surface roughness

Abstract: In this paper, Ni–Co/nano-Al2O3 composite electroforming was used to make the metallic micro-mold for a microlens array. The microstructures require higher hardness to improve the wear resistance and lifetime. Nano-Al2O3 was applied to strengthen the Ni–Co matrix by a new micro-electroforming technique. The hardness and internal stress of Ni–Co/nano-Al2O3 composite deposit were investigated. The results showed that the hardness increased with the increasing Al2O3 content, but at the cost of deformation. Increa… Show more

“…[8][9][10]. Shih reported that nanocomposite electroforming was introduced to produce the microlens array mold by using LIGA [11]. Unfortunately, their present method is only suitable for the fabrication of a micromold, and there is little research concerning the fabrication of large-area functional surface molds using nano-sized particles with a metal matrix.…”
