Question

Galvanized iron sheets are coated with.
A) Copper.
B) Nickel.
C) Zinc.
D) Carbon.

Answer 1

Hint:We know Galvanization is that the process of applying a protective zinc coating to steel or iron, to stop rusting. The foremost common method is hot-dip galvanizing, during which the parts are submerged during a bath of molten hot zinc.

Complete step by step answer:

Galvanization may be a process of coating "Iron or Steel" with Zinc to guard it against the Rusting.
Zinc "weathers at a really slow rate", therefore the coating protects the inner metal and provides it a really long life.
This process intact the steel with full strength and supplies a more delightful appearance.
Zinc features a greater electronegativity than iron and provides selected protection to the "steel from the outer environment"

Therefore, the option C is correct.

Note:
Modern stainless steel may contain nickel, niobium, molybdenum, and titanium in addition to iron, carbon, and chromium. Nickel, niobium, molybdenum, and Chromium improve the corrosion resistance of stainless steel. Thus, stainless steel in addition to iron-nickel and chromium gives tensile strength to the alloy.
Let us see the elements and its purpose which is alloyed with stainless steel.
Carbon: Carbon is alloyed with iron to increase the hardness and strength of iron.
Manganese: Manganese is alloyed to steel to enhance the hot working properties and also to increase toughness and hardenability.
Chromium: Chromium is added to resist the oxidation of iron and the resistance increases with the amount chromium alloyed with the iron.
Nickel: Nickel is added to form the corrosion and heat-resisting steels.
Molybdenum: Molybdenum is added to chromium-nickel alloyed steel to enhance the resistance to pitting and crevice corrosion particularly in chloride and sulfur environments.
Titanium: Titanium is added to increase the carbide stabilization particularly if the material is welded and it reacts with carbon to form titanium carbides which are stable and hard to dissolve in steel.
