ABSTRACT:
A sacrificial anode is made in the form of a disk with a tire made of a sacrificial anodic material. The disk has a central hole which fits over one of two parts to hold the disk in place, as between two telescoping parts, for example. A number of alternative modes of sacrificial anode construction are shown. In some embodiments, conductive or semiconductive plastics are used to provide connections with controlled conductivity.
