Question

What are the values of the current densities used in ECB process?

(a) 0.01 – 0.7 A/cm^2

(b) 0.1 – 7 A/cm^2

(c) 1 – 14 A/cm^2

(d) 21 – 42 A/cm^2

This question was addressed to me by my college professor while I was bunking the class.

My doubt stems from Electrochemical Buffing-Introduction, Material Removal topic in division Hybrid Electrochemical Processes of Advanced Machining

Answer 1

Correct option is (b) 0.1 – 7 A/cm^2

Best explanation: The current densities used in the process of ECB range between 0.1 and 7 A/cm^2.
