Question

Chromium plating is done to make the object scratch proof and appear shiny.
a.) True
b.) False

Answer 1

Hint: The Chromium metal is lustrous in nature. In the electroplating techniques, a thin layer of Chromium metal is coated on the object. This leads to prevention of object scratches, increases the hardness of objects and makes the object appear new.

Complete answer:
Chromium plating is a technique in which the object is covered with a layer of chromium metal. This thin layer prevents the metal from corrosion and scratches. The metal is shiny in nature. So, the object which is covered with this layer appears shiny.
Thus, the statement is true.

Additional information:
The Chromium plating is of two types. It depends on the type of work it is used for.
1. Hard Chrome Plating
It is also called Industrial plating or engineered chrome plating. It is used when a heavy layer of chromium is required on the steel. It is used to preserve the life span of parts. It gives resistance to corrosion and wear of expensive metal objects.
2. Decorative Chrome plating
This type of electroplating gives a thin layer of chromium on the decorative objects. It is used to prevent the expensive decorative objects from corrosion and to provide them a shiny look.

Note:
There are many advantages of chromium plating. It provides hardness to the material. It makes the subject appear shiny and thus so aesthetically pleasing. It is used in restorative work and preservation of expensive engineering parts.
