Описание (английский):

This document specifies the requirements for the contact angle measurement of metallic hydrophobic thin film coatings deposited by the physical vapor deposition (PVD) method, including thermal evaporation, sputtering and ion plating. This document does not apply to non-metallic coatings, paints or varnishes.

Abstract

Overview - ISO 4517:2025 (PVD coatings, contact angle measurement)

Key topics and technical requirements

Measurement principle: Static sessile-drop contact angle measured with a contact angle goniometer; tangent at the three‑phase boundary yields the water contact angle (θ). Hydrophobic: θ > 90°; superhydrophobic: θ > 150°.
Droplet procedure: Place droplet with syringe, record at least five measurements on different positions and report the average. Typical droplet extrusion example: 2 μL; recommended droplet volume range 1–5 μL to avoid gravity/evaporation effects.
Timing since deposition: Metallic PVD coatings evolve in wettability due to hydrocarbon adsorption in air. Measure contact angle at least 7 days after deposition when values stabilize (example: ~100° reported after ~168 h).
Environment control: Perform measurements in ambient air with controlled temperature 20–30 °C and relative humidity 40–60 %; avoid vibrations, strong air flows or bright light during measurement.
Surface quality & morphology: Examine coating topography using AFM, SEM, profilometer. Indicative quality: RMS roughness R < 20 nm within a 5 μm × 5 μm AFM scan; inspect defects at ~300× SEM magnification.
Chemical composition analysis: Use surface-sensitive techniques such as XPS (X-ray photoelectron spectroscopy), EDS, EPMA, Auger to characterize surface chemistry (carbon often present).
Surface free energy: Determine via multiple probe liquids and static contact angles using models such as OWRK; combine with Young’s equation and Wenzel/Cassie–Baxter models to interpret roughness and composite wetting states.

Applications and who uses this standard

ISO 4517:2025 is useful for:

PVD process engineers and R&D teams developing metallic hydrophobic coatings for electronics, aerospace, automotive and construction.
Quality assurance and laboratory personnel performing contact angle testing, surface energy analysis and failure investigations.
Materials scientists and surface chemists comparing wettability across PVD recipes, substrate preparations and post‑treatments. Practical uses include validating hydrophobic performance, optimizing deposition parameters for durability, and ensuring repeatable, comparable wettability data across labs and suppliers.

Related standards and resources

ISO 4517:2025 contains no normative references; users should consult national standards bodies and ISO resources for related guidance on surface analysis and instrumentation. Recommended characterization techniques include AFM, SEM, XPS and contact angle goniometry best practices.
