Tensile & Shear Adhesion Testing
Comprehensive mechanical evaluation determining static tensile bond strength and interfacial shear resistance for calcium phosphate (HA) and porous metallic coatings.
Evaluates adhesion strength between coating and substrate under perpendicular tensile load.
Determines interfacial shear strength and failure mechanics under pure parallel shearing forces.
Stereological Characterization & Prep
End-to-end metallographic preparation and quantitative stereological evaluation assessing porous coating morphology, void fraction, and trabecular depth.
- Mean Thickness (平均厚度): 100 μm – 600 μm
- Porosity Level (孔隙率): 30% – 50% void fraction
- Pore Intercept (孔隙截距): Interconnected pathways
Equipped with low-speed diamond cut-off, vacuum cold mounting resins, automated grinding/polishing stations to prevent edge deformation.
Surface Roughness Profilometry
High-resolution contact stylus profilometry analyzing micro- and macro-surface textures on grit-blasted substrate pre-treatments and as-sprayed medical coatings.
Rules and procedures for assessing profile texture parameters including Ra, Rz, and Rt with precision diamond-tip stylus.
Verification of surface roughness post-alumina grit blasting ensures reproducible interfacial mechanical locking before VPS/APS plasma deposition.
