Abstract
MÉTODOS DE MICROPOLIMENTO DE UMA SUPERFÍCIE DE UMA PEÇA DE TRABALHO DE METAL NÃO FERROSO E DE REMOÇÃO DE MATERIAL DE SUPERFÍCIE CONTROLADA SUBSTANCIALMENTE UNIFORME SOBRE UMA PEÇA DE TRABALHO DE METAL NÃO FERROSO. Uma solução aquosa de eletrólito incluindo uma concentração de ácido cítrico na faixa de cerca de 1,6 g/l a cerca de 982 g/l e uma concentração efetiva de bifluoreto de amônio (ABF); e sendo substancialmente isenta de um ácido forte. Métodos de micropolimento de superfície de uma peça de trabalho de metal não ferroso incluindo expor a superfície a um banho de uma solução aquosa de eletrólito incluindo uma concentração de ácido cítrico na faixa de cerca de 1,6 g/l a cerca de 780 g/l e u ma concentração de bifluoreto de amônio na faixa de cerca de 2 g/l a cerca de 120 g/l e tendo não mais do que cerca de 3,35 g/l de ácido forte; controlar a temperatura do banho para ficar entre o ponto de congelamento e o ponto de ebulição da solução; conectar a peça de trabalho a um eletrodo anódico de uma fonte de alimentação de CC e imergir um eletrodo catódico da fonte de alimentação de CC no banho; e aplicar uma corrente através do banho.
