Abstract: This paper presents the results of nanoscratch tests conducted on adhesive bond thickness, analyzed in terms of material property heterogeneity within adhesive bonds. Nanoscratch tests were performed on adhesive layers made from rigid and elastic adhesives with thicknesses of 0.05 mm and 0.1 mm, under constant load conditions. Penetration depth and residual depth results were analyzed for potential varia-tions in hardness along the adhesive layer thickness. The findings clearly indicate some differences in the material properties of adhesive layers within bonded joints. These results can also be correlated with the phenomenon of apparent Young's modulus, which involves changes in modulus values across the adhesive bond thickness. These findings are crucial for understanding phenomena affecting the consti-tution of adhesive joints, enabling enhancements in their reliability and durability.
