Description: Zinc plating is an electroplating or hot-dip process that deposits a zinc layer on the substrate surface, typically 5-25μm thick (electroplating) or 50-150μm thick (hot-dip). The process includes pretreatment (pickling, activation), galvanizing, and post-treatment (passivation or oiling).
Applicable Materials: Steel, iron, zinc alloys, and copper substrates.
Visual Appearance: Silver-gray or bluish-white hues, matte or glossy finish, and rust-resistant appearance.
Advantage
Excellent Corrosion Resistance: The zinc layer sacrificially protects the substrate from atmospheric and aqueous corrosion, extending its service life by 10-20 years.
Eco-Efficient: Low cost, suitable for high-volume rust-proofing of parts such as bolts and brackets.
Good Adhesion: Bonds tightly to steel and resists impact and bending.
Moderate Conductivity: Suitable for electrical grounding and shielding applications.
Environmentally Friendly Options: Chromium-free passivation reduces hazardous materials and allows for easy recycling.
Multiple process options: Uniform electroplating and thick hot-dip coating, flexible to meet specific needs.
Precautions
Hydrogen embrittlement risk: Steel requires a low-hydrogen process and brittleness testing.
Thickness control: Select thickness based on the environment and test for uniformity.
Post-treatment: Passivation for white rust prevention and salt spray resistance testing.
Design considerations: Avoid deep holes that could affect the coating; plan drainage holes (for hot-dip coating).
Quality standards: Comply with ASTM B633 or ISO 2081, checking thickness and adhesion.
Safety measures: Dispose of acidic wastewater and comply with environmental regulations.
