Abstract

The anode characteristic differences of n- and p- type germanium in aqueous solutions has been investigated in the early 1950's. n-type electrodes were always pitted after being made anode above the breakdown potential, whereas p-type electrodes exhibited an electro-polished surface finish. Diamond Like Carbon (DLC) coated germanium has been used extensively as the material of choice in harsh sub-surface and surface seawater environments. It has been widely demonstrated that DLC coated germanium provides limited protection and that electrolytic etching of the germanium still occurs. This paper investigates the corrosion resistance properties of Boron Phosphide on germanium in a naval environment by presenting measured, comparative data from tests and field trials.
