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 without breakdown
• Durability: Titanium-nickel blend dramatically extends cylinder life
• Chemical Resistance: Excellent protection against corrosion
• Smooth Operation: Ultra-low friction reduces wear and improves efficiency
• Optimal Strength-to-Weight Ratio: Perfect balance for professional saws
