Surface Treatment of Metals: A Quick Comparison
Choosing the right surface treatment boosts durability, adhesion, and corrosion resistance—critical for industries like automotive, aerospace, and construction.
🔍 Comparison Table
| Method | Durability | Cost | Best Fit For |
|---|---|---|---|
| PVD | Superior hardness, wear-resistant | High | Thin coatings, tools, electronics |
| Powder Coating | Thick, corrosion-resistant | Cost-effective | Large parts, architectural, color options |
| Anodizing | Excellent for corrosion & wear | Higher upfront | Aluminum/titanium, low maintenance |
| Electroplating | Moderate protection, decorative | Moderate | Shiny finishes, general-purpose |
| Black Oxide / Parkerizing | Needs oiling, moderate durability | Moderate | Machinery and firearm parts |
