Surface Finish Layer Component – Basic Metal Manufacturing

Component Specifications

Definition

A precisely engineered surface treatment applied to forging-grade titanium alloy bar stock, typically through processes like grinding, polishing, or coating, to achieve specific surface roughness, hardness, and chemical resistance properties required for industrial forging applications.

Working Principle

The surface finish layer modifies the outermost material layer through mechanical abrasion, chemical treatment, or deposition techniques to create controlled surface characteristics that improve performance under forging conditions.

Materials

Titanium alloy substrate (typically Ti-6Al-4V or similar forging grades) with surface modifications including oxide layers, nitride coatings, or mechanically worked surface zones.

Technical Parameters

Hardness HRC 35-45
Thickness 5-50 μm
Adhesion Strength >50 MPa
Corrosion Resistance ASTM B117 salt spray >500 hours
Surface Roughness (Ra) 0.4-1.6 μm

Standards

ISO 4287, ISO 21920, ASTM B265, AMS 4928
