Q.Higher current density is usually recommended for

  • ATin platting
  • BCadmium platting
  • CBronze plating
  • DChromium plating
Correct Answer : (D)

Chromium plating

Hints :

Higher current density is usually recommended for Chromium plating.

Usually the chromium plating is the hard surface plating. So, we need to generate the greater temperature to achieve the surface of the object as hard. So, it requires the highest current density such as 325 Amps / feet2 or 35 Amps / m2.
