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

Correct Answer:

The potential at which the sum of all anodic current densities equals the sum of all cathodic current densities

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

Correct Answer:

Activation-controlled (charge-transfer) electrochemical kinetics at high overpotentials

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

Correct Answer:

Linear polarization resistance (LPR) corrosion rate 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

Correct Answer:

Graphically find icorr and Ecorr by locating the intersection of anodic and cathodic polarization curves

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

Correct Answer:

Regions of immunity (below about -0.62 V SHE), passivity (intermediate pH with oxide), and corrosion (low pH or very high pH)
