Abstract

MéTODO ELETROLìTICO PARA OBTENçãO DE NìQUEL NANOCRISTALINO, compreende um método no qual é possível obter depósitos de níquel nanocristalino de altíssima pureza, afinal o método proposto é isento de aditivos orgânicos; o método proposto utiliza corrente pulsada e ajustes que visam variar parâmetros de corrente aplicada, pH, temperatura e agitação da solução para controlar a redução do tamanho de grão; o método ora revelado possibilita a obtenção de níquel nanocristalino com alta pureza e alta resistência mecânica; um dos focos de aplicação do níquel nanocristalino de alta pureza obtido é a microfabricação de componentes que necessitem suportar esforços mecânicos, que poderão ser miniaturizados, beneficiando a indústria eletroeletrónica.Electrolytic method for obtaining nanocrystalline nickel comprises a method in which very high purity nanocrystalline nickel deposits can be obtained, since the proposed method is free of organic additives; The proposed method uses pulsed current and adjustments to vary applied current, pH, temperature and stirring parameters to control grain size reduction; The method now revealed makes it possible to obtain nanocrystalline nickel with high purity and high mechanical resistance; One of the focuses of application of the high purity nanocrystalline nickel obtained is the microfabrication of components that need to support mechanical forces, which can be miniaturized, benefiting the electronics industry.
