Advantages of Zinc Phosphate Coatings
- Corrosion Protection: Zinc Phosphate coatings provide excellent corrosion resistance, protecting the metal substrate from rust and other forms of corrosion
- Lubricity: Phosphating can act as a solid lubricant, reducing friction and wear on metal parts, which is particularly beneficial in applications with metal-on-metal contact, such as with automotive components or machinery
- Paint Adhesion: Zinc Phosphate’s surface texture promotes better paint adhesion, which is especially useful in industries like automotive manufacturing, where paint quality and durability are critical
- Oil Retention: Phosphating can retain oil or other lubricants within their porous structure, providing additional lubrication for moving parts, which is valuable in applications where continuous lubrication is required
- Improved Wear Resistance: the presence of Zinc Phosphate can improve the wear resistance of metal parts, increasing their longevity and reducing maintenance requirements
Zinc Phosphate Process at Greystone
Greystone applies Zinc Phosphate coatings through a meticulously controlled process to ensure uniform coating weight, smooth grain structures, excellent surface adhesion, corrosion resistance, and long-term performance. Our process includes:
- Surface Preparation: components undergo tumbling, blasting or chemical cleaning prior to Phosphating to remove contaminants and optimize surface reactivity
- Grain Refiners are utilized to ensure a tight control over grain structure, improving component appearance and performance
- Immersion Phosphating: Parts are treated in a phosphating solution through either Rack or Barrel coating to develop a consistent, crystalline Zinc Phosphate layer
- Post-Treatment: Depending on application needs, oiling, baking, or sealing treatments are applied to enhance corrosion resistance, lubricity, or adhesion properties
- Quality Assurance: Our in-house laboratory testing includes coating weight verification, salt spray testing, and adhesion testing to ensure compliance with industry standards
