Chemistry

Not quite remember

I easily remember

Rusting of iron speeds up when it comes into contact with metal such as (1)

Rusting of iron speeds up when it comes into contact with metal such as (2)

Rusting of iron speeds up when it comes into contact with metal such as (3)

Ways to prevent rusting (1)

Use of protective surface

Ways to prevent rusting (2)

Sacrificial protection

Ways to prevent rusting (3)

Alloying

Prevent rusting by using alloying method (1)

In stainless steel, iron is alloyed with carbon, chromium and nickel

Prevent rusting by using alloying method (2)

Chromium and nickel create a shiny, protective and corrosion proof oxide layer

Prevent rusting by using alloying method (3)

The oxide layer formed protects the iron from being exposed to water and oxygen to prevent rusting
