What is Titanikel Plating?
Titanikel plating is a sophisticated technology developed by Hyway, involving a blend of titanium and nickel applied through a high-temperature steam plating process at 900 to 1000 degrees Celsius. This creates a robust, wear-resistant surface perfect for engine components.
Titanikel Plating Process:
The process starts with multi-composite electroplating, coating the cylinder with a titanium-nickel composite. After plating, the surface is polished with diamond tools to achieve an exceptionally smooth finish due to titanium's high strength.
Benefits of Titanikel Plating:
- High Temperature Resistance: Can handle extreme temperatures, ensuring the cylinder remains intact under heavy use
- Durability: The titanium-nickel combination enhances wear resistance, significantly extending cylinder life
- Chemical Resistance: Titanium's natural resistance protects against environmental factors
- Smooth Operation: Ultra-smooth finish reduces friction, improving efficiency and reducing wear on other components
- Optimal Strength-to-Weight Ratio: Balances high strength and low weight, crucial for chainsaw performance
Compatibility:
- Stihl 044 (12 mm piston pin models only)
- Stihl MS440 (all versions)
Will NOT fit early 044 with 10 mm pin
