1.Define Corrosion: The deterioration of a substance, usually a
metal from a reaction with its environment
2.What is Passivation?: A layer of oxides formed on the surface of a
metal that provides corrosion protection.
3.What is an example of passivation?: Stainless Steel
4.What are the elements of a corrosion cell?: Anode, Cathode, Metallic
Path- way, Electrolyte
5.Describe what happens at the anode.: The metal dissolves into the
electrolyte
6.What is the function of the electrolyte?: Allows the passage of ions to
connect the corrosion cell
7.What is the function of the metallic pathway?: Allows the flow of
electrons to connect the corrosion cell
8.What is the galvanic series?: A listing of metals in order of reactivity
(more or less noble) in seawater at 25 C 9.The general rules of galvanic corrosion are:: The more reactive metal -- when connected to the less reactive (more noble) metal -- will corrode preferentially 10.Name the five (5) most important factors that affect the *rate of
corro- sion.*: Humidity, oxygen, chemical salts, pollutants,
temperature 11.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 12.Localized corrosion is:: At discrete/specific spots on the metal surface. Typi- cally pitting and crevice corrosion. The most concerning as damage is concentrated and loss of integrity or structural failure can result.
13.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
14.How does NACE define the Inspector's role?: The inspector's role is
that of a 1 / 3

*quality control technician* responsible for *observing and reporting conformance or deviation from the project specification.* 15.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. 2 / 3

16.Name some tests that may need to be conducted during surface prepa-
ration and coating operations.: Ambient Temperature, Relative Humidity
& Dew Point, Anchor Profile, Surface Cleanliness 17.Name some of the documentation/reports that may be required to be
maintained on a coatings project.: Daily/weekly summary, material
usage re- ports, manpower and equipment, conformance, and Non- conformance
18.What are the most important characteristics of a good report?:
Objective, Accurate, and Detailed.
19.What is the inspector's primary responsibility and what should the in-
spector 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.
20.What type of information could you expect to find on a [Material]
Product Data Sheet (PDS)?: 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.
21.What type of information could you expect to find on a Safety Data
Sheet?: Health, safety and environmental. The PPE required. Physical
character- istics. Emergency responder information.
22.Explain the difference between Quality Assurance (QA) and Quality
Con- trol (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 performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer 23.Identify some of the defects that can be caused by incorrect
application temperatures.: Failure to cure, too rapid solvent
evaporation, poor film formation
24.Describe relative humidity.: The amount of moisture in the air
compared to saturation level
