| Process | Surface Characteristics | Color Option | Roughness |
|---|---|---|---|
Electroplating | Uniform metallic coating; adjustable gloss (matte / bright) | Partial colors available (color Zn, black Zn); fixed gold/silver | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Surface Decoration Processes | Decorative patterns / logos; high-gloss or special texture coating | Fixed decorative colors (gold, silver) | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Electrophoresis | Uniform corrosion-resistant organic coating; matte / semi-gloss / gloss | Yes (black, white, custom colors) | Ra1.6, Ra3.2 or per 2D drawing |
Engraving / Marking | Permanent logos, patterns, text; engraved or color-changed | No (base material color or oxidation only) | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Decorative Chrome Plating | High-reflection mirror/semi-bright silver; wear-resistant, durable | No (standard silver mirror) | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Mechanical Polishing | Remove burrs, tool marks, oxide; uniform matte surface | No (base material color) | Ra0.4 – Ra3.2 (process dependent) |
Blackening / Phosphating | Black/dark gray conversion coating; improved corrosion & adhesion | Blackening: fixed black; Phosphating: natural color | Ra1.6, Ra3.2 or per 2D drawing |
As-Machined | Retain machining lines; only deburr & edge break | No (base material color) | Standard Ra3.2; optional Ra1.6 / Ra0.4 |
Brushing | Clear unidirectional texture; premium matte appearance | No (enhances base color) | Standard Ra3.2; texture thickness optional |
Polishing | Smooth from matte to mirror; eliminates machining marks | No (boosts natural gloss & reflectivity) | Custom: Ra1.6, Ra0.8, Ra0.4 (mirror) |
Sand Blasting | Uniform matte/frosted texture; clean & improve adhesion | No (retains base color) | Standard Ra3.2 (related to grit size) |
Spray Painting | Rich colors, gloss (matte/semi-gloss/gloss), textures; decorative + protective | Yes (full custom colors & effects) | Standard Ra3.2; gloss optional |
Powder Coating | Thick, uniform, wear-resistant; smooth/textured; excellent weatherability | Yes (custom colors & textures) | Standard Ra3.2; gloss & texture optional |
Anodizing (Type II) | Hard corrosion-resistant oxide film; colorable; matte/semi-gloss/gloss | Yes (black, red, blue, green, natural) | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Heat Treatment | Improves hardness, strength, wear resistance; may oxidize (except bright/vacuum) | No (no decorative color; oxide or natural) | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Hard Anodizing (Type III) | Ultra-thick, hard, ceramic-like oxide; insulating, heat & wear resistant | Limited (dark gray, black, or sealed natural) | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Vacuum Plating / PVD Coating | Ultra-thin, hard, wear-resistant film; metallic colors (gold, black) | Yes (TiN gold, MoS2 black, etc.) | Ra0.4, Ra0.8, Ra1.6 or per 2D drawing |
Screen Printing / Pad Printing | Clear logos, patterns, text; strong adhesion | Yes (multi-color & custom graphics) | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Special Functional Coating | Extreme performance: high hardness, low friction (DLC), biocompatibility | Fixed (DLC = black); function-oriented | Per 2D drawing (high Ra base required) |
Electropolishing | Ultra-smooth mirror finish; removes micro-burrs; improves corrosion resistance | No (enhances metallic luster) | Up to Ra0.8 or finer |
Quench-Polish-Quench (QPQ) | Matte black surface; extreme hardness, wear & corrosion resistance | Standard matte black | Ra0.8, Ra1.6, Ra3.2 or per 2D drawing |
Teflon (PTFE) Coating | Smooth non-stick, low-friction, chemical resistant | Yes (black common) | Standard Ra3.2 |
Passivation & Alodine | Thin color/colorless conversion film; corrosion resistance; paint base | Alodine: color/clear; Passivation: clear | Base Ra maintained (Ra0.4–Ra3.2) |
Special & Advanced Processes
| Process | Surface Characteristics | Color Option | Roughness | Key Function / Notes |
|---|---|---|---|---|
Vapour Polishing | Glass-like smooth, clear, high-gloss surface | No | Ultra-high finish | Mirror finishing for plastic parts |
Microarc Oxidation (MAO) | Thick, hard, porous ceramic oxide; insulating, heat & wear resistant | Yes (colorable) | Porous matte | Ceramic conversion for light alloys |
Conductive Paint Spraying | Conductive surface for EMI shielding / ESD protection | Black / gray typical | Per drawing | Functional coating (non-decorative) |
