Cathodic Protection

Cathodic Protection Specialists Perth

Cathodic protection describes a method which is used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. This involves a simple method of connecting the metal which is to be protected to a more easily corroded “sacrificial metal” to act as the anode.

Types of Cathodic Protection.

There are two types of Cathodic Protection.

Galvanic protection

This refers to the application of protective zinc coating that is applied to steel to prevent rusting. This type of protection has limited life spans, as the underlying metal will degrade over time.

Impressed Current Cathodic Protection

This refers to positively charged electrons that are connected to a power source that provides an electrical flow. This type of protection is stronger and often long-lasting due to its unlimited electrical power source.

Setbacks of Cathodic Protection

Cathodic protection has been used for years to stop corrosion. However, it can require routine maintenance and replacement based on the ongoing level of corrosion present in the structures environment.
