Answer:
the electrode at which reduction occurs. electrons flow towards the cathode in the external ciruit
●● cathodic protection.
Answer:
A technique to reduce the corrosion of a metal surface by making that surface the cathode of an
electrochemical cell.
●● corrosion.
Answer:
the deterioration of a material, usually a metal, that results from a reaction with its environment.
●● corrosion inhibitor.
Answer:
A chemical substance or combination of substances that, when present in the environment, prevents
or reduces corrosion.
●● crevice corrosion.
Answer:
localized corrosion of a metal surface at, or immediately adjacent to, an area that is shielded from
the environment and full exposure due to the close proximity of the metal to another surface
●● electrolyte.
Answer:
A chemical substance that promotes conduction of an electrical current
●● galvanic series.
,Answer:
List of metals and alloys arranged according to their corrosion potentials in a given environment (in
sea water at 25 celcius)
●● generalized corrosion.
Answer:
Corrosion that is distributed more or less uniformly over the surface of a material
●● localized corrosion.
Answer:
Occurs at discrete sites and often in areas that are difficult to inspect
●● mill scale.
Answer:
The oxide layer formed during hot fabrication or heat treatment of metals.
●● Passivation.
Answer:
a layer of oxides formed on the surface of a metal that provides corrosion protection (ex stainless
steel)
a reduction of the anodic reaction rate of an electrode involved in corrosion,
●● Pitting Corrosion.
Answer:
Localized corrosion of a metal surface that is confined to a small area and takes the form of cavities
called pits.
●● Return Path (Metallic Pathway).
Answer:
Connects the anode and cathode, allowing passage of electrons, generated at the anode, to the
cathode
●● what are the elements of a corrosion cell.
Answer:
,1. Anode 2.
Cathode 3. Metallic pathway 4. Electrolyte
●● what happens at anode.
Answer:
oxidation. metal dissolves into electrolyte
●● what is the function of the electrolyte.
Answer:
Allows the passage of ions to connect the corrosion cell
●● what is the function of the metallic pathway.
Answer:
Allows the flow of electrons to connect the corrosion cell
●● The general rules of galvanic corrosion are:.
Answer:
The less noble (or more reactive) metal when connected to a more noble (or less reactive metal)
will corrode preferentially
●● name at least 5 factors that affect the rate of corrosion.
Answer:
temp, humidity, chemical salts, oxygen, pollutants
●● General Corrosion.
Answer:
Uniform loss of material over an entire surface and general thinning of affected surface
corrosion that is distributed more or less uniformly
does not cause catastrophic failures
●● Localized Corrosion.
Answer:
Occurs at discrete sites and often in areas that are difficult to inspect.
concentrated and can cause catastrophic failures
, ●● what are some of the common tools/methods used for corrosion control.
Answer:
inhibitors, design, cathodic protection, protective coatings, splash zone systems, altering the
environment
●● Coatings Specification.
Answer:
Formal, structured document containing information on a project (scope, terms, schedule,
inspection, etc.)
●● Instrument Calibration History Reports.
Answer:
Reports that normally contain information on how frequently each instrument is to be or has been
calibrated.
●● Materials Inventory Reports.
Answer:
Reports that contain information on the inventory of jobsite materials, and are normally submitted
periodically
●● safety data sheets (SDS sheets).
Answer:
a form containing data of known substances in a particular product
●● Quality insurance (QA).
Answer:
any systematic process that checks whether a manufactured product or service being developed is
meeting specified requirements
●● quality control (QC).
Answer:
