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?
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?
Safety enforcement is not the responsibility of the inspector; however, it is his/her responsibility to
report any issues that may affect the project.
Name some tests that may need to be conducted during surface preparation and coating operations.
Temperature, Relative Humidity, Dew Point, Anchor Profile, Surface Cleanliness
Name some of the documentation/reports that may be required to be maintained on a coatings project.
Daily/weekly summary, material usage reports, manpower and equipment, non conformance, and
conformance
What are the most important characteristics of a good report?
Objective, Accurate, and Detailed.
What is the inspector's primary responsibility and what should the inspector not do as it pertains to the
specification.
The Inspector's primary responsibility as the inspector is to "enforce" specification. The inspector is NOT
to make changes to the specification for any reason.
What type of information could you expect to find on a Product Data Sheet?
Surface preparation and application information such as recommended level of surface cleanliness,
recommended application methods and equipment such as tip sizes. Also, environmental parameters for
application such as max and min temperatures, curing times, recoat windows.
What type of information could you expect to find on a Safety Data Sheet?
Health, safety and environmental. The PPE required. Physical characteristics. Emergency responder
information.
Explain the difference between Quality Assurance (QA) and Quality Control (QC).
Quality Assurance - Any systematic process of checking to see whether a product or service being
developed is meeting specs.
Quality Control - A procedure or set of procedures intended to ensure that a manufactured product or
