Define Corrosion Right Ans - The deterioration of a substance, usually a
metal from a reaction with its environment
What is passivation? Right Ans - A layer of oxides formed on the surface of
a metal that provides corrosion protection.
What is an example of passivation? Right Ans - Stainless Steel
What are the elements of a corrosion cell? Right Ans - Anode, Cathode,
Metallic Pathway, Electrolyte
Describe what happens at the anode. Right Ans - The metal dissolves into
the electrolyte
What is the function of the electrolyte? Right Ans - Allows the passage of
ions to connect the corrosion cell
What is the function of the metallic pathway? Right Ans - Allows the flow of
electrons to connect the corrosion cell
What is the galvanic series? Right Ans - A listing of metals in order of
reactivity (more or less noble) in seawater at 25 C
The general rules of galvanic corrosion are: Right Ans - 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.
Right Ans - Humidity, oxygen, chemical salts, pollutants, temperature
General corrosion is: Right Ans - 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: Right Ans - 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. Right
Ans - Design, Inhibitors, Material Selection, Cathodic Protection, Protective
Coatings, Splash Zone Systems, Alteration of the Environment
How does NACE define the inspector's role? Right Ans - 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?
Right Ans - 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. Right Ans - 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. Right Ans - Daily/weekly summary,
material usage reports, manpower and equipment, non conformance, and
conformance
What are the most important characteristics of a good report? Right Ans -
Objective, Accurate, and Detailed.
What is the inspector's primary responsibility and what should the inspector
not do as it pertains to the specification. Right Ans - 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?
Right Ans - 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.
