•Surface modified fillers improve adhesion to the metal substrate.•Adhesion is evaluated using the Vikers method and the appropriate model.•The analysis of the indent shape can carry information about adhesion quality. The objective of this study is to investigate quantitative assessment of the adhesion behavior of composite films onto a metallic surface. The composite films had UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as matrix and ferrous oxide doped alumina (Al2O3 Fe) particles with two surface modifications, (3-methacryloxypropyltrimethoxysilane) (MEMO) and the vinyltris(2-methoxyethoxy)silane (VTMOEO), as reinforcement. Composites were made with 0.5, 1.5 and 3 wt% of alumina particles. Adhesion was evaluated using the micro hardness testing method. The contact angle was measured and compared to the adhesive parameter from micro hardness measurements. The form of the indent on the surface of the composite film was analyzed in order to correlate the indent morphology to the adhesion quality.
