MATSE 201 FINAL QUESTIONS AND ANSWERS 2025

MATSE 201 FINAL LATEST
cathodic - ANSWERS-type of protection where a more reactive metal is
added to material of concern


anodic - ANSWERS-type of protection where an external power source
is used to decrease current density, used in storage of highly corrosive
materials


galvanic - ANSWERS-two different metals are coupled in corrosive
environment in this type of corrosion


anodic, cathodic - ANSWERS-anodic/cathodic metal will dissolve and
anodic/cathodic metal will be passivated in galvanic corrosion


further - ANSWERS-the closer/further the metals are on the galvanic
series the stronger the driving force for corrosion is


design, insulating, and decreasing cathode area - ANSWERS-three ways
of preventing galvanic corrosion are


reduction - ANSWERS-as you go up the galvanic series, this potential
increases

oxidation - ANSWERS-as you go down the galvanic series, this
potential increases


zinc - ANSWERS-in a galvanic cell, this is the anode


copper - ANSWERS-in a galvanic cell, this is the cathode


crevice corrosion - ANSWERS-this type of corrosion occurs when a
solution is trapped inside


crevice - ANSWERS-nuts, bolts, and rivets all experience this type of
corrosion


crevice - ANSWERS-metal to metal crevice corrosion is in a
crevice/gasket


gasket - ANSWERS-metal to nonmetal crevice corrosion is in a
crevice/gasket


crevice - ANSWERS-this type of corrosion is readily seen in stainless
steel
