Manufacturing Insight: Titanium Nitride Coating Service
Elevate Component Performance with Honyo’s Integrated Titanium Nitride Coating Service
Honyo Prototype delivers precision-engineered solutions where surface integrity directly impacts functional longevity and operational efficiency. Our specialized Titanium Nitride (TiN) coating service enhances critical components with exceptional hardness (up to 2400 HV), superior wear resistance, and reduced friction coefficients—ideal for demanding applications in aerospace, medical devices, and precision tooling. This advanced PVD coating process deposits a uniform, gold-hued layer (typically 0.25–4.0 μm thick) that significantly extends tool life while maintaining tight geometric tolerances.
This capability is intrinsically linked to our core CNC machining expertise. Honyo’s multi-axis milling and turning centers produce substrates with optimal surface finishes and dimensional accuracy, ensuring flawless adhesion and performance of the TiN layer. Unlike standalone coaters, we control the entire value stream—from raw material machining through final coating—eliminating supply chain variables that compromise coating integrity. Our engineers optimize both the machined substrate geometry and the coating parameters to meet your specific wear, corrosion, or biocompatibility requirements.
Leverage this integrated approach to transform prototypes or production runs into high-reliability components without outsourcing coordination. Accelerate your development cycle immediately using Honyo’s Online Instant Quote platform. Upload CAD files to receive precise, transparent pricing for combined CNC machining and TiN coating services within hours—enabling faster iteration and time-to-market for performance-critical parts.
Technical Capabilities
Titanium Nitride (TiN) coating is a high-performance surface treatment used to enhance the wear resistance, hardness, and thermal stability of cutting tools and precision components. This service is particularly beneficial in advanced machining environments involving 3/4/5-axis milling and turning operations where tight tolerances are critical. TiN coating improves tool life and maintains dimensional accuracy during prolonged use, especially when machining abrasive or tough materials such as steel, aluminum, ABS, and nylon.
The coating is applied using Physical Vapor Deposition (PVD), ensuring a uniform, dense, and adherent layer with minimal dimensional change—typically between 2 to 4 microns thick. This makes it ideal for components requiring tight tolerance control (±0.0001″ or better) and high surface finish integrity.

From CAD to Part: The Process
Honyo Prototype’s titanium nitride (TiN) coating service follows a rigorously defined workflow designed for precision, efficiency, and technical validation. This integrated process ensures optimal coating performance while minimizing lead times for industrial clients.
CAD Upload and Geometry Analysis
Clients initiate the process by uploading CAD files through our secure portal. Our system performs immediate automated geometry validation, checking for critical parameters such as part complexity, surface curvature, and feature accessibility. This initial scan identifies potential coating uniformity challenges, such as deep recesses or sharp edges where line-of-sight deposition in physical vapor deposition (PVD) systems may be compromised.
AI-Powered Quoting Engine
The validated CAD data feeds into our proprietary AI quotation system. Unlike generic volume-based quoting, our algorithm analyzes surface area, geometric complexity, required coating thickness (typically 2–5 µm for TiN), and substrate material compatibility. It cross-references historical production data to predict masking requirements, fixture design complexity, and thermal distortion risks during the 450–500°C PVD process. Clients receive a detailed quote within 2 business hours, including technical feasibility notes and lead time estimates.
Engineering DFM Review
All projects undergo mandatory Design for Manufacturing (DFM) review by our coating engineering team. This phase addresses TiN-specific constraints:
| DFM Consideration | Honyo’s Action | Technical Rationale |
|---|---|---|
| Substrate Material | Verify compatibility with TiN adhesion (e.g., reject 300-series stainless without intermediate layer) | TiN requires diffusion bonding; incompatible substrates cause delamination |
| Geometric Tolerances | Flag features requiring custom fixturing (e.g., internal diameters < 5mm) | PVD line-of-sight limitations necessitate rotational fixturing for uniform coverage |
| Thermal Sensitivity | Assess risk of warpage in thin-walled components (>0.5mm deflection threshold) | 500°C process temperature may exceed yield strength of some alloys |
| Edge Definition | Recommend radius adjustments for sharp edges (min. 0.2mm) | Prevents edge thinning and micro-arc defects during plasma activation |
Production Execution
Approved projects move to production in our Class 10,000 cleanroom facility. The TiN coating process follows this sequence:
Substrate preparation includes precision grit blasting (Al₂O₃, 80–120 µm) followed by ultrasonic cleaning in multi-stage alkaline and solvent baths. Parts then undergo vacuum chamber loading with custom-designed fixtures to ensure optimal angular exposure. The PVD process uses reactive magnetron sputtering with high-purity titanium targets in nitrogen-argon atmosphere, maintaining strict control of parameters: 480°C ±5°C substrate temperature, 3.5 Pa chamber pressure, and 2.5 µm/hr deposition rate. Real-time optical emission spectroscopy monitors plasma stability to prevent stoichiometric deviations.
Quality Control and Delivery
Post-coating, every batch undergoes:
Adhesion testing per ASTM C1624 (scratch test > 45N critical load)
Hardness verification (2400±200 HV via ISO 14577)
Thickness uniformity mapping (ellipsometry at 5+ points per part)
Salt spray validation (ASTM B117, 120+ hours for 316L stainless substrates)
Final documentation includes a material traceability report, coating certification with batch-specific test data, and as-coated dimensional analysis. Parts ship in anti-static, humidity-controlled packaging with delivery confirmation via our logistics portal within 7–10 business days from DFM sign-off.
This closed-loop process guarantees TiN coatings meeting ISO 2819 and ASTM B648 standards while providing clients with full technical transparency from quotation through certification.
