Abstract

Overview

ISO 13779-4:2018 specifies a laboratory test method for measurement of adhesion strength of hydroxyapatite (HA) coatings applied to metallic substrates of surgical implants. The standard defines how to prepare coated coupons, assemble a bonded test specimen, apply a uniaxial tensile load, record maximum load at failure and calculate adhesion strength (σ = F / A). It is intended for quality control, batch release, R&D and regulatory documentation for implants for surgery.

Key topics and requirements

Test principle: tensile testing of a cylindrical test assembly (coated coupon bonded to an uncoated counterface) with load applied normal to the coating plane.
Apparatus:
- Mechanical testing machine with load capacity ≥ 30 kN and accuracy ±2% of full scale (verify per ISO 7500-1).
- A loading assembly that minimizes off-axis loading (pins/yoke arrangement illustrated in the standard).
Test specimens:
- Coated coupons nominal diameter 24.8–25.6 mm (tolerance
