Our Surface Process Spectrum
Three distinct titanium surface modification workflows — from precision anodizing through high-voltage plasma ceramic deposition to deep chemical surface preparation.
Aerospace & Medical Anodizing
Executing strict AMS 2488 Type II anti-galling conversions and Type III aesthetic/functional color-coding loops without toxic pigments.
- AMS 2488 Type II anti-galling anodizing for threaded fasteners & sliding interfaces
- Type III color-coding anodizing (gold, blue, purple, green) for medical & aerospace traceability
- Zero toxic pigment electrolyte formulations — environmentally compliant closed-loop baths
- Controlled dielectric breakdown thresholds for precision coating thickness (±2 µm)
Micro-Arc Oxidation / MAO
Driving high-voltage plasma discharge arrays to grow thick, ultra-hard in-situ titanium oxide ceramic skins to counter severe abrasive sliding wear.
- Plasma-assisted anodizing at 400–600 V DC generating micro-discharge plasma channels
- In-situ TiO₂ ceramic layer growth up to 50 µm+ with micro-hardness exceeding 1000 HV
- Exceptional abrasive wear resistance — Taber abrasion index < 5 mg/1000 cycles
- Uniform coating on complex 3D geometries and internal blind holes via electrolyte bath circulation
Acid Pickling & Passivation
Utilizing precise multi-stage HNO₃-HF chemical baths to completely strip away brittle alpha cases and foreign iron tracking to restore raw anti-corrosion bounds.
- Controlled HNO₃-HF ratio baths (15–25% HNO₃, 2–5% HF) precisely tailored per titanium grade
- Complete alpha case removal from forged/machined surfaces — depth control within ±5 µm
- Iron contamination elimination to < 0.05 µg/cm² per ASTM A380 & ASTM F86 standards
- Post-pickling passivation restores native TiO₂ passive layer for maximum corrosion resistance
Surface Performance Dashboard
Our titanium surface processing limits — validated processing depths, micro-hardness matrix, and strict global compliance benchmarks.
Oxide Film Thickness
Micro-controlled coating domains matching from 0.5 µm up to heavy 50 µm+ ceramic boundaries — tailored per application via precise voltage and bath chemistry regulation.
Surface Micro-Hardness
MAO processing capability spiking raw titanium hardness up to 600–1000 HV limits — transforming ductile substrates into wear-resistant ceramic surfaces.
Salt Spray Endurance
Resisting extreme corrosive environment testing exceeding 1,000+ hours zero-pitting boundaries per ASTM B117 standards — validated by accredited third-party laboratories.
Quality Compliance
100% interlocked under ISO 13485 medical, AMS 2487/2488D, and ASTM F86 parameters — full material traceability with batch-level certification documentation.
All specifications measured under ISO 2768-m, ASTM B117, and AS9100D controlled conditions. Actual results depend on titanium grade, geometry complexity, and surface preparation.
Anti-Galling & Osseointegration Engineering
Two critical titanium surface challenges — conquering cold-welding in mechanical assemblies and engineering bio-active pore topologies for implant integration.
Interlocking Anti-Galling Barriers
Titanium's high coefficient of friction (µ ≈ 0.5–0.6 against itself) combined with its adhesive wear tendency causes severe cold-welding and thread locking under torque, leading to catastrophic joint failure in aerospace fasteners and medical implant assemblies.
Alkaline Type II Anodization — Dynamic Lubricious Titanate Crystal Layers
- Alkaline-based Type II anodizing (AMS 2488) generates a porous, lubricious titanate crystal surface with inherent self-lubricating properties
- Friction coefficients slashed by 60% (down to µ ≈ 0.2) — transforming galling-prone titanium interfaces into reliable, repeatable sliding surfaces
- Controlled anodic layer thickness of 2–5 µm eliminates micro-weld nucleation sites while maintaining dimensional tolerances within ±2 µm
- Verified via MIL-DTL-8937 thread galling torque testing — zero seizure events across 25+ re-torque cycles
Biomimetic SLA Topography
Smooth machined titanium surfaces (Ra < 0.5 µm) fail to establish adequate mechanical interlock with bone tissue, resulting in fibrous encapsulation, delayed osseointegration, and increased implant loosening risk over the long term.
Large-Grit Blasting + Dual Hot-Acid Etch — Micro-Nano Compound Pore Matrices (Ra 2.0–4.0 µm)
- Primary large-grit corundum blasting (250–500 µm Al₂O₃) generates macro-roughness peaks and valleys (Ra 3.0–5.0 µm) for immediate mechanical bone interlock
- Dual hot-acid etching (H₂SO₄/HCl sequence at 80–100°C) creates superimposed nano-pores (50–200 nm diameter) that mimic natural osteoclast-resorbed bone topography
- Final micro-nano compound surface achieves Ra 2.0–4.0 µm with >90% interconnected porosity — optimized for osteoblast cell adhesion, proliferation, and differentiation
- In-vitro studies demonstrate 3.2× greater osteogenic gene expression vs. machined controls, accelerating clinical osseointegration timelines by up to 40%
Every titanium surface engineering project is backed by certified process documentation, in-house metallurgical analysis, and continuous quality monitoring. Surface science meets clinical reliability.
