The specific volume ratios of W, Cr and Ni are 3.6, 2.0 and 1.6 respectively. Which of them will have the least rate of corrosion?
(a) Ni
(b) Cr
(c) W
(d) All will have the same rate of corrosion
The question was posed to me in unit test.
My doubt stems from Factors Influencing Corrosion topic in chapter Corrosion, Electrolysis, Fuel Cells and Batteries of Engineering Chemistry II
