Cathodic protection snapshot

Name of technique

Cathodic protection

Use

Prevent corrosion
Complement protection given by coatings

Definition

A technique where an ionic current towards the structure from the electrolyte is used to counter the corrosion current flowing out of the structure.

CP criteria

CP potential of -850 mV vs. CSE
An instant off potential of at least -850 mV vs CSE
A minimum 100 mV polarization post instant off

CP measurement techniques

Soil resistivity
CIPS
DCVG
Line current

Factors affecting CP requirements

pH
velocity
ionic type
ionic concentration
temperature

Issues with CP

Stray current corrosion
Insufficient CP potential
Insufficient CP current
Electrical shorting

I will discuss all these with examples in this major course, where you can prepare for the basics for your certification course!

Corrosion risk planning - 1 - Lead acid battery

Corrosion is a quality, environment, and safety issue. Hence, it has to come under the cope of integrated management system audits However at the moment, it is more or less considered a quality issue. As such, the general tendency is to solve corrosion issues as they come. Especially in new inventions, the foresight to look for potential corrosion risk gets lost in the attempt to focus and highlight the amazing qualities of the said inventions. Hence, I have initiated this series, where I will take a component and point out the potential corrosion and damage risk areas. Here goes the first one - lead acid battery cell. (Source:https://opentextbc.ca/chemistry/chapter/17-5-batteries-and-fuel-cells/) Protective casing - effect of temperature + electrolyte + contamination in electrolyte on the polymer crevice corrosion at fixtures mechanical damage during handling leading to voids for moisture ingress and oxygen/electrolyte leakage Positive terminal - corrosion of the mate...
