Stainless steel does not rust because , a. Cr and Ni combine with Fe ....
**Explanation:**
Stainless steel is a corrosion-resistant material that does not rust like regular steel does. This is due to the presence of chromium (Cr) in stainless steel, which forms a thin, protective oxide layer on the surface of the steel. Below are the detailed reasons why stainless steel does not rust:
**1. Chromium and Nickel Alloy:**
- Stainless steel is primarily composed of iron (Fe), along with chromium (Cr) and often nickel (Ni).
- The presence of chromium and nickel in stainless steel alloys enhances its corrosion resistance properties.
- Chromium and nickel combine with iron to form a stable protective layer on the surface of the steel, preventing rusting.
**2. Formation of a Protective Oxide Layer:**
- Chromium is the key element that provides stainless steel its corrosion resistance.
- When chromium in stainless steel is exposed to oxygen in the atmosphere, it reacts to form a thin, transparent oxide layer called chromium oxide (Cr2O3).
- This oxide layer acts as a barrier, preventing further oxidation of the underlying iron.
- The chromium oxide layer is self-repairing and can reform if damaged or scratched, providing ongoing protection against rust.
**3. Passivation Process:**
- Stainless steel undergoes a process called passivation to enhance its corrosion resistance.
- Passivation involves treating the stainless steel surface with an acid solution to remove any contaminants or free iron.
- This process promotes the formation of a thicker and more protective chromium oxide layer on the surface.
**4. Other Factors:**
- Nickel, often present in stainless steel, also contributes to its corrosion resistance.
- Nickel improves the stability and durability of the protective oxide layer formed by chromium.
- The combination of chromium and nickel in stainless steel alloys enhances their resistance to corrosion caused by various environmental factors such as moisture, chemicals, and salt.
In summary, stainless steel does not rust because of the presence of chromium and, in some cases, nickel. Chromium forms a protective oxide layer that prevents the underlying iron from coming into contact with oxygen and moisture, thus inhibiting rust formation. The passivation process further enhances the corrosion resistance of stainless steel.
