NACE CIP Level 1 Study Guide Questions With
Correct Answers
Define |Corrosion |- |CORRECT |ANSWER✔✔-The |deterioration |of |a |substance, |usually |a |metal |
from |a |reaction |with |its |environment
What |is |passivation? |- |CORRECT |ANSWER✔✔-A |layer |of |oxides |formed |on |the |surface |of |a |
metal |that |provides |corrosion |protection.
What |is |an |example |of |passivation? |- |CORRECT |ANSWER✔✔-Stainless |Steel
What |are |the |elements |of |a |corrosion |cell? |- |CORRECT |ANSWER✔✔-Anode, |Cathode, |Metallic |
Pathway, |Electrolyte
Describe |what |happens |at |the |anode. |- |CORRECT |ANSWER✔✔-The |metal |dissolves |into |the |
electrolyte
What |is |the |function |of |the |electrolyte? |- |CORRECT |ANSWER✔✔-Allows |the |passage |of |ions |to
|connect |the |corrosion |cell
What |is |the |function |of |the |metallic |pathway? |- |CORRECT |ANSWER✔✔-Allows |the |flow |of |
electrons |to |connect |the |corrosion |cell
What |is |the |galvanic |series? |- |CORRECT |ANSWER✔✔-A |listing |of |metals |in |order |of |reactivity |
(more |or |less |noble) |in |seawater |at |25 |C
, The |general |rules |of |galvanic |corrosion |are: |- |CORRECT |ANSWER✔✔-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. |- |CORRECT |
ANSWER✔✔-Humidity, |oxygen, |chemical |salts, |pollutants, |temperature
General |corrosion |is: |- |CORRECT |ANSWER✔✔-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: |- |CORRECT |ANSWER✔✔-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. |- |CORRECT |ANSWER✔✔-
Design, |Inhibitors, |Material |Selection, |Cathodic |Protection, |Protective |Coatings, |Splash |Zone |
Systems, |Alteration |of |the |Environment
How |does |NACE |define |the |inspector's |role? |- |CORRECT |ANSWER✔✔-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? |- |CORRECT |
ANSWER✔✔-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. |- |CORRECT |ANSWER✔✔-Temperature, |Relative |Humidity, |Dew |Point, |Anchor |
Profile, |Surface |Cleanliness
