2.4 Lebensmittelverarbeitung
- Ausrüstung & Behälter: The smooth nickel coating is easy to clean and resists bacteria. Dairy farms use coated milk tanks to meet hygiene standards.
2.5 Medizinische Ausrüstung
- Chirurgische Instrumente: Scalpels and forceps stay sharp and rust-free. Hospitals report coated tools last 2x longer than uncoated stainless steel.
- Implantate: Orthopedic screws use biocompatible nickel coatings—they don’t react with body fluids, reducing infection risks.
2.6 Marine
- Ship Components & Offshore -Strukturen: Propellers and oil rigs use coated steel to fight saltwater corrosion. A North Sea oil rig has used coated parts for 15 Jahre mit minimaler Wartung.
3. Manufacturing Techniques for Nickel Steel Coated
Erstellennickel steel coated products involves four key steps. Each step is tailored to enhance the material’s properties:
3.1 Stahlherstellungsprozesse
Erste, the base steel is made using:
- Elektrischer Lichtbogenofen (EAF): Melts scrap steel with electricity—fast and eco-friendly (used for 70% of coated steel).
- Basis -Sauerstoffofen (Bof): Converts iron ore to steel—ideal for large batches (Z.B., für Schiffsschmerzen).
3.2 Wärmebehandlung
Heat treatment optimizes the base steel’s strength:
- Quenching & Temperieren: Cools steel quickly (Quenching) then reheats (Temperieren) to boost hardness without brittleness. Used for engine components.
- Glühen: Heats steel slowly to reduce stress—critical for forming parts like exhaust pipes.
- Niederschlagshärtung: Adds fine particles to the steel to increase strength (used for aerospace parts).
3.3 Bildungsprozesse
The steel is shaped into final products using:
- Heißes Rollen: Rolls steel at 1000°C to make sheets/plates (Z.B., Für Lagertanks).
- Kaltes Rollen: Rolls at room temperature for a smooth finish (used for surgical instruments).
- Stempeln: Presses steel into shapes (Z.B., Kfz -Körperteile) ohne zu knacken.
3.4 Oberflächenbehandlung
Endlich, the nickel coating is applied:
- Nickel Plating: Two methods—electroplating (uses electricity for even coating, ideal for small parts) and electroless plating (chemical reaction, great for complex shapes like turbine blades).
- Additional Coatings: Some products get a second layer (Z.B., Titannitrid for extra hardness or Verchromung for shine).
- Schuss sich angeren: Blasts small metal balls at the surface to add compressive stress—boosts fatigue resistance.
4. Fallstudie: Nickel Steel Coated in Aerospace Gas Turbines
A major aerospace company testednickel steel coated gas turbine blades in commercial jet engines over 5 Jahre. Here’s what they found:
- Leistung: Coated blades had 15% less oxidation (rust from high heat) than uncoated blades. This kept engine efficiency high (no drop in thrust over time).
- Haltbarkeit: Coated blades needed replacement every 8,000 flight hours—vs. 6,500 hours for uncoated blades. Diese senkte die Wartungskosten um 20%.
- Sicherheit: No blade failures occurred during testing—critical for passenger safety.

FAQ
- Is nickel steel coated safe for medical implants?
Yes—medical-grade nickel steel coated uses biocompatible nickel alloys that don’t react with body fluids. It’s widely approved for implants like orthopedic screws. - Can nickel steel coated be painted or welded?
It can be welded (using TIG or MIG methods) without damaging the coating. Painting is possible too, but the nickel layer already resists corrosion—painting is usually for aesthetics only. - How long does the nickel coating last?
In milden Umgebungen (Z.B., indoor equipment), the coating can last 10–15 years. In harsh conditions (Z.B., Salzwasser), it lasts 5–8 years with regular maintenance (Z.B., Reinigung).
