PVD Colored Stainless Steel Sheet Production Process
The production of colored stainless steel sheets via PVD (Physical Vapor Deposition) involves three core stages: pre-treatment, PVD coating deposition, and post-treatment, with strict parameter control throughout.
1. Pre-Treatment (Substrate Preparation)
This stage ensures a clean, smooth surface for coating adhesion.
Cutting & Polishing: Cut stainless steel coils/plates to required dimensions via laser or shearing. Polish with abrasive belts/wheels to achieve finishes like mirror, brushed, or matte, and remove minor scratches.
Cleaning: First, degrease with alkaline/solvent solutions to eliminate oil and fingerprints. Then, pickle with nitric-hydrofluoric acid to remove oxide layers and polishing residues. Finally, rinse with deionized water and dry with hot air/infrared to avoid water spots.
2. PVD Coating Deposition (Color Formation Core)
Completed in a high-vacuum chamber to ensure coating quality.
Vacuum Setup: Load dried substrates into the chamber, then pump to 10⁻³–10⁻⁵ Pa (high vacuum). Heat substrates to 150–300°C and use argon ion bombardment for deep cleaning.
Target Sputtering & Reaction: Select targets based on color (e.g., titanium for gold, chromium for silver). Use magnetron sputtering (plasma bombards targets to release atoms) or arc ion plating (electric arc melts targets) to vaporize targets. Introduce reactive gases (nitrogen for nitrides, oxygen for oxides); target atoms react with gases to form colored compound films (e.g., TiN for rose gold) on substrates.
Thickness Control: Monitor via a quartz crystal sensor to keep coating thickness at 0.1–1 μm (too thin = poor fastness; too thick = brittleness).
3. Post-Treatment & Inspection
This stage enhances performance and ensures compliance.
Cooling & Finishing: Cool the chamber to room temperature, release vacuum, and unload. Optionally, lightly polish coated surfaces for better gloss.
Quality Checks: Test coating hardness (≥2000 HV via Vickers tester) and adhesion (no peeling via cross-cut tester). Use a spectrophotometer to verify color consistency (ΔE ≤ 1 vs. standards).
Packaging: Wrap qualified sheets in anti-scratch film, then pack in cartons/wooden pallets for transport.
Advantage
Hot-rolled stainless steel coils in grades 201, 304, 430, and 316 deliver unmatched versatility for industrial and structural applications.
