A need for trouble-free electrode holders for corrosion studies at high temperature and high pressure has existed for a long time. B. E. Wilde1 has recently reviewed the different types of electrode holders which are currently in use for this purpose. D. G. Damin2 has updated the review. The most popular of the many designs is the various adaptations for the classic Stern-Makrides3 type holder. All of these types have one or more problems associated with them. They often fail during tests because of either crevice corrosion or electrical insulation breakdown, etc. We present here a new electrode holder design which has successfully been used in our laboratory for some time. Furthermore, this design is easy to fabricate.
Before we present the new design, let us first consider the problems associated with the Stern-Makrides type adaptation. Figure 1 shows the details of a popular adaptation of the...
