Product Description
Detailed Specifications & Features
Waved Spring Surface Treatment Options - Phosphating, Dacromet & More
Surface treatment is a critical factor in determining the durability, corrosion resistance, and performance of waved springs across industrial applications. SUNZO offers a comprehensive portfolio of surface finishing solutions tailored to specific operating environments, ensuring optimal functionality in aerospace, precision machinery, and hydraulic seal systems.
Surface Treatment Options
Plain Oiled
- Process: Light coating of mineral oil applied via immersion or spray, forming a temporary protective barrier
- Performance: Provides 90+ days of corrosion protection in dry indoor environments (per ASTM D1748 humidity testing) and reduces friction by 15% compared to untreated surfaces
- Ideal For: Cost-sensitive indoor applications with minimal moisture exposure, such as conveyor systems and general industrial machinery
Phosphating
- Process: Chemical conversion coating forming a crystalline layer of iron phosphate (5-10μm thickness)
- Performance: Enhances corrosion resistance (500+ hours of neutral salt spray per ASTM B117) and improves lubricity, reducing friction by 25% for smooth operation in dynamic assemblies
- Ideal For: Hydraulic seal systems, precision gearboxes, and automotive components requiring wear resistance
Blackening (Alkaline Oxidation)
- Process: Alkaline solution treatment creating a uniform Fe₃O₄ layer (5-8μm thickness)
- Performance: Achieves 500+ hours of salt spray resistance, increases surface hardness (HV 450-550), and provides cleanroom compatibility
- Ideal For: Medical devices, semiconductor equipment, and precision instruments in controlled environments
Mechanical Zinc Plating
- Process: Electroplated zinc coating (8-12μm thickness) applied via mechanical deposition
- Performance: Delivers 800+ hours of salt spray resistance (ASTM B117), enhances wear resistance by 35%, and extends service life by 200% in abrasive conditions
- Ideal For: Heavy-duty industrial applications, including hydraulic cylinders and offshore machinery
Dacromet Coating
- Process: Chromate-free zinc-aluminum flake coating with inorganic binders
- Performance: Industry-leading corrosion protection (1,000+ hours salt spray resistance), outperforming traditional zinc plating by 300% in coastal or high-humidity environments
- Ideal For: Aerospace components (landing gear, engine systems) and marine equipment exposed to extreme weather
