Define Corrosion
The deterioration of a substance, usually a metal from a reaction with its environment
What is passivation?
A layer of oxides formed on the surface of a metal that provides corrosion protection.
What is an example of passivation?
Stainless Steel
What are the elements of a corrosion cell?
Anode, Cathode, Metallic Pathway, Electrolyte
Describe what happens at the anode.
The metal dissolves into the electrolyte
What is the function of the electrolyte?
Allows the passage of ions to connect the corrosion cell
What is the function of the metallic pathway?
Allows the flow of electrons to connect the corrosion cell
What is the galvanic series?<\/p>\n\n\n\n
A listing of metals in order of reactivity (more or less noble) in seawater at 25 C
The general rules of galvanic corrosion are:
The less noble (or more reactive) metal when connected to a more noble (or less
reactive metal) will corrode preferentially
Name the five most important factors that affect the rate of corrosion.
Humidity, oxygen, chemical salts, pollutants, temperature
General corrosion is:
Results in a relatively uniform loss of material over the entire surface, Results in a
general thinning of the affected surface, Relatively easy to inspect, Does not casue
catastrophic failures
Localized corrosion is:
Typically pitting and crevice corrosion. It is typically of the most concern as damage is
concentrated and loss of integrity or structural failure can result.
List some of the common tools\/methods used for corrosion control.
Design, Inhibitors, Material Selection, Cathodic Protection, Protective Coatings, Splash
Zone Systems, Alteration of the Environment
How does NACE define the inspector’s role?
The inspector’s role is that of a quality control technician responsible for observing and
reporting conformance or deviation from the project specification.
What is the inspector’s responsibility when it comes to safety on the project?<\/p>\n","protected":false},"excerpt":{"rendered":"
