8 Questions
How does 'overvoltage' affect the corrosion rate of a metal in the galvanic series?
Lowers the effective electrode potential of the metal
How does the physical state of metals influence corrosion?
Smaller grain size increases corrosion
In what type of medium does metal corrosion occur faster according to the text?
Acidic conditions
How does humidity impact the corrosion of metals based on the text?
Increases corrosion rate
What determines the rate and severity of corrosion in metals according to the text?
The difference of electrode potentials or positions of the metals in the galvanic series
Why does corrosion at the anodic region occur at a faster rate when dissimilar metals are in contact in a corrosive medium?
Because the anodic metal is higher up in the galvanic series
Which metal corrodes faster when in contact with copper in a medium according to the text?
Zinc
What is the best example provided in the text to illustrate faster corrosion?
Defective surface coating of tin on iron metal
