由于航空工业的发展,要求能在钢及铝合金上生成紧密的与底层附着力很好的电镀层。但由于这类金属的负电位高,容易在空气中氧化以及与电镀溶液起作用等缺点,所以对这类金属及合金的电镀存在着很大的困难,特别是要得到与底层附着力很好的电镀层。本文通过用“复浸锌法”和“浸锌法”(详见下面)的比较,证明用复浸锌的方法,完全能得到比“浸锌法”抗蚀性能高,结合力好的电镀层。而且还诸述了解决粘合力的关键问题和能在锅上直接镀铬的工艺规程。 Due to the development of the aeronautical industry, it is required to be able to produce a close plating layer with excellent adhesion to the bottom of steel and aluminum alloy. However, due to the negative potential of these metals is high, easy to oxidation in the air and the role of the plating solution and other shortcomings, so the plating of such metals and alloys there is a big difficulty, especially to get good adhesion with the underlying Plating layer. In this paper, we compare the “immersion zinc method” and “zinc immersion method” (see below) to prove that the method of re-soaking zinc can completely get the better corrosion resistance than the “zinc immersion method” Floor. But also describes the key issues of adhesion and process specifications that can be chrome plated directly on the pan.
