“…The objective of this work is to grade systems (adherend/adhesive/ surface treatment) based on results obtained with the 3-point bending test [3] as well as to assess the effects of substrate thickness with this test. The purpose is to be able to compare the intrinsic adherence of systems, whatever the thicknesses of components are, and also to get a better understanding of the mechanics of this test.…”

“…Bonding is an assembly method widely used in nautical and aeronautical industries, as well as in car manufacturing and construction [1][2][3][4][5]. However, the adhesion between an adhesive and the substrate is yet to be fully understood: this lack of understanding continues to be a major obstacle to the use of adhesive bonding technology in critical systems.…”

This is an author-deposited version published in : http://oatao.univ-toulouse.fr/ Eprints ID : 17849 A B S T R A C TThe increasing use of adhesives in industry has boosted the search for tests which allow the adherence level to be defined. These tests, depending on the type of load, examine different stresses, failure modes and mixed modes. Furthermore, these tests can be focused either on initiation or propagation of adhesive failure. The subject of this study is the initiation of adhesive failure. The initiation of failure can be determined with the 3-point bending test. Trials of 3-point bending tests were conducted on an aluminum 2024 substrate, with two different thicknesses, in order to understand the impact of the adherend thickness. The aluminum substrate received different types of surface pre-treatment: acetone cleaning, hydrochloric acid etching or aminopropyltriethoxysilane coating. Two adhesives were used: the first one was a mixture of epoxy pre-polymer DGEBA and DETA amine, whereas the second was a commercially formulated adhesive, ELECOLIT 6604. The initiation of adhesive failure was obtained by 3-point bending test and verified with SEM analysis. The failure loads measured enabled the effect of surface treatment on adhesive failure to be revealed: the results indicate that the surface treatment with silane is the most efficient in comparison to hydrochloric acid etching and of course to the simple acetone degreasing. It was assumed that the scatter of the results obtained for each series is due to the variation of the "intrinsic" adherence between the adhesive and the substrate. Furthermore, it was noted that the failure loads for different substrate thicknesses cannot be compared due to the effect of the thickness: it was therefore not possible to simply compare results obtained for different thicknesses of the same substrate for a given substrateadhesive system. The energy approach proposed in this study makes it possible. The energy requested to initiate the adhesive failure for a given system can then be known, whatever the initial geometry of the 3-point bending test is. However, it was also shown that the thickness of the substrate must be correctly chosen. A thick substrate increases the dispersion and a thin substrate may induce local unwelcome plastic strain. In conclusion, this study allows to define an energy criteria for adhesives failure initiation.

“…It has a significant impact on the selection of a surface preparation technique and its application. Surface preparation of titanium and titanium alloys for adhesive bonding usually involves the use of chemical treatment operations such as etching in sulfuric or nitric acid [4,18], anodizing [16,19], degreasing [18,20], and priming [14,21]. The latter is more frequently used, because in sulfuric acid etching, one can observe hydrogen adsorption by titanium.…”

“…[15]. Golaz et al [18] investigated the different surface treatment of titanium (degreasing sandblasting, etching, anodizing) in various configurations in the context of ageing conditions and durability of bonded joints of Ti6Al4V titanium alloy. A combined surface treatment of sanding, degreasing, and chemical etching showed the best durability, whereas a treatment using an additional sulphuric anodic oxidation showed the best adhesion before ageing.…”

This study investigated the effect of the different surface treatment methods on the strength of Ti6Al4V titanium alloy sheet adhesive joints. The following surface treatment methods were used: alkaline degreasing, anodizing, vibratory shot peening, and anodizing with vibrational shot peening. The following tests/measurements were carried out during the experiment: surface roughness measurements; microhardness measurements (conducted by the Vickers hardness test method); and strength tests of single-lap adhesive joints fabricated with the use of two epoxy adhesives, rigid and flexible, both based on epoxy resin Epidian 5. It has been found that the application of anodizing followed by vibratory shot peening leads to increased strength of adhesive joints, irrespective of the type of applied epoxy adhesive.
