Question

Nitride made the metals a) corrosion resistant b) wear resistant

Answer 1

nitride made the corrosion resistant

Answer 2

Answer: a. corrosion

Nitriding is a surface modification process done in some metals so as to make them resistant against the corrosion, wear and breakage. In this process, the nitrogen is coated over the surface of the metal. The nitrogen atoms reacts with the atoms of the metal surface which results in the production of the nitrides. The metallic nitrides are hard and usually resists corrosion and wear.
