摘要:
Electrical contacts having good corrosion resistance. These contacts may include a set of three layers. The three layers may include a first or top layer and two layers below the top layer. The second or middle layer may be more electrochemically active than either the first layer or the third layer. The first layer may include cracks, pores, or other discontinuities. Corrosive substances may pass through these cracks, pores, and other discontinuities and corrode the second, more electrochemically active layer below the first layer. The cracks, pores, and other discontinuities may spread the corrosion homogenously and laterally across the surface of the contact, thereby protecting the remainder of the contact.
