Inspection Facilities at BLW – A Leading Liquid Nitriding Service Provider in Delhi NCR
Liquid nitriding is a diffusion process that transforms the surface of metal components. Nitrogen atoms integrate with the material, creating a highly durable surface that resists wear, flaking, and peeling, ensuring enhanced longevity.
Surface Integration
The diffusion process ensures the nitrided layer becomes part of the base material, providing a robust, wear-resistant surface.
Corrosion Resistance
The nitrided and oxidized surface exhibits excellent corrosion resistance, making it suitable for demanding environments.

What is the difference between Liquid Nitriding and Liquid Carbo Nitriding?
Liquid Nitriding
Chemical Composition:
This process primarily introduces nitrogen atoms into the surface of the metal. The liquid medium used contains nitrogen-rich salts, which diffuse nitrogen into the metal's surface.
Resulting Properties:
The primary result is a hardened case with excellent wear resistance and surface hardness. It also enhances fatigue strength. This makes it suitable for parts like valves and gears, where wear resistance is crucial.
Applications:
Commonly used for components that need high wear resistance but may not necessarily need high toughness, such as gears, shafts, and certain types of bearings.
Liquid Carbo Nitriding
Chemical Composition:
This process introduces both nitrogen and carbon atoms into the metal surface. The liquid medium contains a combination of nitrogen and carbon-bearing compounds, leading to the diffusion of both elements into the surface.
Resulting Properties:
This process results in a case that not only has improved surface hardness and wear resistance but also increased toughness and impact resistance due to the presence of carbon. It's ideal for parts like springs and pins, which require high-impact resistance.
Applications:
Preferred for parts that require a balance of wear resistance and toughness, such as springs, pins, and fasteners that are subjected to high-impact loads.
In summary, the main distinction lies in the elements diffused into the metal and the resulting mechanical properties, with liquid nitriding focusing more on wear resistance and liquid carbo-nitriding enhancing both wear resistance and toughness.
