Anode Biofilm | IntechOpen
2013/10/4· Introducing a pH-sensitive fluoroprobe into the anode chaer revealed a strong pH gradient within the G. sulfurreducens anode biofilm. The pH decreased with increased proximity to the anode surface and from the exterior to the interior of the biofilm pillars. pH levels near the anode surface were as low as 6.1 compared to pH 7 near the hode.

Offshore sacial anode design -- A producers view of …
Offshore sacial anode designs that could in theory provide an optimized solution are in practice constrained by design limiting factors. Limiting factor recommendations are made for Platform and Bracelet anodes together with the introduction of crack propensity (CPR) indiors that can be used to predict maximum anode length which may be successfully manufactured by good foundry practice.

Overview of hodic Protection | Inspectioneering
Without CP, metals act as the anode and easily lose their electrons and thus, the metal becomes oxidized and corroded. CP simply supplies the metal with electrons from an external source, making it a hode. Basic Terminology Oxidation — Loss of Anode
