1. Material Overview: Composition to Characteristics

Cobalt-Chromium-Molybdenum (CoCrMo) alloy is a metal material with cobalt (Co, 58-65%) as the base, supplemented by chromium (Cr, 26-30%), molybdenum (Mo, 5-7%), and trace elements like carbon/nickel. Originating in the 1930s for jet engine turbine blades (e.g., Vitallium®), it now underpins critical medical and industrial applications.

Key Properties:

• ⚙️ Wear Resistance: High hardness (HRC 25-40) + self-lubrication against friction
• 🛡️ Corrosion Resistance: Chromium oxide layer shields against bodily fluids, acids, and seawater
• 🔥 Thermal Stability: Maintains strength at 730–1100°C, resisting thermal fatigue/oxidation
• ❤️ Biocompatibility: ISO 5832-4/ASTM F75 certified for long-term human implants

2. Medical Field: Engineering Life Renewal

Orthopedic & Dental Innovations:

• Hip/Knee Implants: Forged CoNiCrMo alloy offers 400–600 MPa fatigue strength + 30+ year lifespan
• Spinal Fixation: Vacuum investment casting minimizes defects for anatomical precision
• Dental Solutions: Vitallium® frameworks provide strength-elasticity balance (nickel/beryllium-free) Innovation Spotlight: China’s "Dragon Knee" joint adapts to Asian skeletal anatomy.

3. Industrial Excellence: Defying Extreme Environments

• ✈️ Aerospace: Stellite® alloys protect turbine blades at 870°C
• ⛽ Energy/Chemical: Resists sulfur corrosion in subsea valves/seals; extends coal nozzle lifespan 3x
• 🧪 Surface Engineering: Laser-clad CoCrMo-based high-entropy films (Zr/Nb-doped) boost corrosion resistance by 40%

4. Advanced Manufacturing Breakthroughs

• 🔨 Casting: Vacuum melting + hot isostatic pressing (HIP) eliminates porosity
• 🏗️ Forging: Hot-forged CoNiCrMo achieves >20% elongation for load-bearing implants
• ⚡ Precision Machining: Cubic boron nitride (CBN) tools cut spherical joints (25 parts/tool)
