Sample Questions

Question 1
In mixed-potential theory, the corrosion potential (Ecorr) of a freely corroding metal is:
The potential at which the sum of all anodic current densities equals the sum of all cathodic current densities
The thermodynamic reversible potential of the most noble half-reaction
Always equal to the hydrogen electrode potential
The average of the open-circuit potentials of anodic and cathodic reactants
Question 2
The Tafel equation (η = a + b·log(i)) describes:
The concentration of reactants at steady state
Activation-controlled (charge-transfer) electrochemical kinetics at high overpotentials
The thickness of a passive film
The diffusion coefficient of oxygen
Question 3
The Stern-Geary equation icorr = B / Rp, where B = (ba·bc)/(2.303(ba+bc)), is used in:
Galvanic series ranking
Linear polarization resistance (LPR) corrosion rate measurement
Pourbaix diagram construction
Paint film thickness measurement
Question 4
An Evans (Pourbaix-like) diagram plotting E vs log(i) is used to:
Show the mass-loss of coupons
Graphically find icorr and Ecorr by locating the intersection of anodic and cathodic polarization curves
Measure the thickness of rust
Compare paint colors
Question 5
Which of the following correctly describes the Pourbaix diagram for iron at 25°C?
A single corroding region over all pH
Regions of immunity (below about -0.62 V SHE), passivity (intermediate pH with oxide), and corrosion (low pH or very high pH)
Only a passive region
Only a corroding region
