Processo para eletrodeposição catódica de um material metálico selecionado em um substrato permanente ou temporário e microcomponente produzido por um processo de eletrodeposição de pulso

摘要

The invention relates to a process for forming coatings or free-standing deposits of nanocrystalline metals, metal alloys or metal matrix composites. The process employs drum plating or selective plating processes involving pulse electrodeposition and a non-stationary anode or cathode. Novel nanocrystalline metal matrix composites and micro components are disclosed as well. Also described is a process for forming micro components with grain sizes below 1,000nm.
