Kolsterization® Surface hardening: Nitriding and special treatments for screws and fasteners
Surface hardening (Kolsterization®), such as nitriding and other special treatments, are fundamental processes to improve the wear, fatigue and corrosion resistance of fasteners and mechanical components. These processes increase surface hardness without compromising the toughness of the core, ensuring high performance even under extreme conditions.
Nitriding: maximum hardness and durability
Nitriding is a thermochemical treatment that enriches the surface of the metal with nitrogen, forming very hard compounds that improve resistance to wear and corrosion. Key benefits include:
- Increased surface hardness, ideal for heavy-duty mechanical applications.
- Improved wear and fatigue resistance without significant dimensional deformations.
- Reduced friction for more efficient performance in coupling systems.
Special treatments for Fasteners
In addition to nitriding, there are other advanced treatments that optimize the mechanical properties of the components:
- Carburizing: enriches the surface with carbon, improving wear resistance.
- PVD and CVD coatings: deposit ultra-thin protective layers to reduce friction and corrosion.
- Black oxidation and phosphating: Improve corrosion protection and lubricant adhesion.
Kolsterization®: Industrial applications
These treatments are used in industries, where the quality and durability of the components are essential.
