Question

name a metal that can form a layer of oxide on its surface and becomes non -reactive​

Answer 1

Explanation:

Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder.[1] It is used to add mild corrosion resistance, for appearance and to minimize light reflection.[2] To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax.[3] One of its advantages over other coatings is its minimal buildup.[2]
