Question

how can rusting be prevented write five methods

Answer 1

Five methods of preventing rust :

➡️ Coating iron articles with zinc (galvanisation).

➡️ By painting

➡️ By greasing and oiling.

➡️ By converting into stainless steel.

➡️.. By usind wax to prevent contact with moist air.

Answer 2

$\huge\mathfrak\red{Answer :}$


$\huge\textbf{Rusting :}$


When a iron came in contact with oxygen and air then it develop a thick coating around itself which is known as Rusting.


$\huge\textbf{Prevention :}$


→ Galvanization is a process in which the iron sheets are coated with a layer of zinc which prevents rusting. Zinc gets oxidized more readily than Iron. Due to this Iron remains protected and prevent rusting.

→ Painting the Iron surface will create a barrier between the Iron and the atmosphere, which will protect the Iron from rusting.

→ By electroplating.

→ By oiling and greasing.

→ By alloying to make it stainless steel.
