Wear and Corrosion Resistant Fittings

We have developed a nano-modified anti-corrosion surface treatment technology. By integrating alloy deposition and composite deposition, and optimizing the heat treatment of fitting substrates, the product’s corrosion resistance is greatly enhanced.

Technical Features and Advantages:
  • Strong coating adhesion: A new co-deposition model based on interfacial forces between nascent metal and particles improves coating-substrate bonding strength.
  • High substrate corrosion resistance: This new heat treatment process, designed based on phase transformation, optimizes microstructure and grains for better corrosion resistance.
  • Excellent coating corrosion resistance: A new multi-component complexing system, developed via quantitative analysis of alloy deposition complexing agents, creates varied complex effects on Zn²⁺ and Ni²⁺. It raises zinc content in coatings and improves bath stability and coating uniformity.
  • Energy saving & emission reduction: The surface treatment is conducted at room temperature, avoiding zinc melting required in hot-dip galvanizing, delivering significant carbon reduction benefits.
