查询词典 Zn

The research shows that In has activation to Al, making its corrosive potential decrease, and increasing the rate of H2-evolutive simultaneously. The affiliating of Zn leads In and Al to alloying, reducing the rate of H2-evolutive, and passivating aluminum. The adhibiting of Bi helps to activate Al electrode, but gets up the rate of H2-evolutive. The existent of Pb passivates Al anode, restraining the H2-evolutive availably. After compounding these elements, the general performances of complex alloys are advanced by their conjunct functions farther.

结果表明，铟对铝阳极有活化作用，使铝的腐蚀电位发生负移，但同时也会加大析氢副反应的速度；锌的加入促进了铟的合金化，减少富铟偏析相的形成，而且能极大地降低铝阳极的析氢反应速率，使其钝化；铋的引入有助铝阳极活化，但同时又会导致析氢速率的提高；铅的存在使铝阳极钝化，有效地抑制了析氢反应，但加大了阳极极化。
