1. Purpose of Shaft Surface Treatment
Surface treatment for shaft parts serves the following purposes:
- Improve Wear Resistance: Increase surface hardness, extend service life
- Corrosion Resistance: Resist environmental corrosion, maintain precision
- Reduce Friction Coefficient: Reduce wear, improve transmission efficiency
- Improve Appearance: Beautify surface, enhance product grade
- Restore Dimensions: Repair after wear, restore use
2. Electroplating
Electroplating is the most common surface treatment for shafts:
Chrome Plating
- Hardness: HV 800-1000
- Thickness: 0.01-0.05mm
- Advantages: High hardness, good wear resistance, low friction coefficient
- Applications: Hydraulic piston rods, printing machine rollers
Nickel Plating
- Hardness: HV 400-500
- Thickness: 0.01-0.03mm
- Advantages: Good corrosion resistance, attractive appearance
- Applications: Food machinery shafts, medical device shafts
Zinc Plating
- Hardness: Relatively low
- Advantages: Low cost, good rust prevention
- Applications: General drive shafts, structural shafts
3. Heat Treatment
Heat treatment improves overall shaft performance:
Quenching and Tempering
- Process: Quenching + high temperature tempering
- Hardness: HRC 28-32
- Advantages: Balance of strength and toughness
- Applications: 45# steel, 40Cr shaft parts
Induction Hardening
- Process: Induction heating + quenching
- Hardness: HRC 55-62 (surface)
- Advantages: High surface hardness, tough core
- Applications: Gear shafts, drive shafts
Carburizing
- Process: Carburizing + quenching + low temperature tempering
- Hardness: HRC 58-62 (surface)
- Advantages: High surface hardness, good wear resistance
- Applications: 20CrMnTi gear shafts
4. Surface Hardening
Surface hardening treatments for local hardness improvement:
- Nitriding: Surface hardness HV 1000-1200, minimal deformation
- Carbonitriding: Combine carburizing and nitriding advantages
- Laser Hardening: Local hardening, minimal deformation
5. Surface Finishing
Surface finishing to improve surface quality:
- Polishing: Mechanical polishing, Ra0.2 or better
- Grinding: Precision grinding, Ra0.1 or better
- Superfinishing: Super finishing, Ra0.05 or better
- Rollling: Improve surface hardness, enhance fatigue performance
6. Surface Treatment Selection
Select appropriate surface treatment based on application needs:
- High Wear Resistance: Chrome plating, induction hardening, carburizing
- Corrosion Resistance: Nickel plating, zinc plating, stainless steel
- High Precision: Grinding, superfinishing
- Low Cost: Zinc plating, quenching and tempering
