Start with the base material, service environment, critical dimensions, and required performance.
Protection contre la corrosion
Select protection according to moisture, chemicals, salt exposure, and outdoor service.
Wear & Hardness
Specify contact pressure, sliding motion, target hardness, and expected service life.
Appearance & Texture
Define color, gloss, texture, grain direction, and approved visual standards.
Fits & Critical Surfaces
Control coating allowance, masking, threads, sealing faces, and final dimensions.
Chemical & Electrochemical Finishes
These processes add corrosion protection, controlled color, conductivity, hardness, or a functional metallic layer.
Placage électrolytique
Metal coatings for corrosion resistance, conductivity, wear control, or appearance.
Anodisation
Protective and decorative oxide finishes for aluminum, including hard anodizing.
Alodine Finish
Thin conversion coating for aluminum requiring corrosion protection and conductivity.
Nickelage
Metallic nickel coating for corrosion, wear, dimensional restoration, or conductivity.
Passivation
Removes free iron and supports the corrosion resistance of stainless steel parts.
Revêtement par électrodéposition
Uniform protective coating for conductive metal parts and complex geometries.
Finitions mécaniques
Mechanical processes control texture, reflectivity, edge condition, and tactile appearance.
Polissage
Reduces surface roughness and produces a smooth or reflective finish.
Brossage
Creates a controlled directional grain on visible metal surfaces.
Sablage
Cleans, profiles, and creates uniform matte textures with controlled abrasive media.
moletage
Adds a patterned gripping surface to knobs, shafts, handles, and fasteners.
Protective & Specialty Processes
These treatments protect the substrate, prepare it for coating, or modify material performance.
Oxyde noir
Low-build black conversion finish for ferrous components and precision dimensions.
Phosphatation
Steel pretreatment for corrosion protection, lubrication, or coating adhesion.
Painting & Powder Coating
Colored barrier coatings for appearance and environmental protection.
Traitement thermique
Controls hardness, strength, toughness, wear performance, and dimensional stability.
Autres finitions de surface courantes
Additional processes are selected according to material, function, production quantity, and acceptance requirements.
| Finition de la surface | Utilisation type |
|---|---|
| Sablage de perles | Creates a fine matte texture and reduces light machining marks. |
| Vibratory Finishing | Deburrs and smooths small metal or plastic parts in production batches. |
| Grenaillage de précontrainte | Introduces compressive residual stress to improve fatigue performance. |
| PVD or DLC Coating | Adds a thin hard layer for wear resistance, low friction, or color. |
| Revêtement en PTFE | Provides low friction, release properties, and chemical resistance. |
| Revêtement en paillettes de zinc | Protects steel fasteners and components in corrosive service. |
| Marquage au laser | Adds permanent part numbers, logos, and traceability codes. |
Adapter le procédé au matériau de base
Confirm the exact material grade, heat-treatment state, and required performance before selecting a finish.

Préciser la finition avant la production
Clear requirements protect critical features and establish consistent acceptance standards.
Épaisseur du revêtement
Define allowable buildup on diameters, holes, threads, and mating surfaces.
Masquage
Mark bearing seats, sealing faces, electrical contacts, and untreated areas.
Norme cosmétique
Specify color, gloss, texture, grain direction, or an approved limit sample.
Inspection
Define checks for thickness, adhesion, roughness, color, corrosion, and dimensions.
