“…These results are coherent according to what has been described by Zhang et al., 33 who reported a contact angle of 46° for samples modified by PEO. In another study, 14 they showed that topography and roughness dictate the surface-free energy and wettability. To probe this, they studied changes in the contact angle in samples of abraded Mg at different grades.…”

The optimal mechanical properties render magnesium widely used in industrial and biomedical applications. However, magnesium is highly reactive and unstable in aqueous solutions, which can be modulated to increase stability of reactive metals that include the use of alloys or by altering the surface with coatings. Plasma electrolytic oxidation is an efficient and tuneable method to apply a surface coating. By varying the plasma electrolytic oxidation parameters voltage, current density, time and (additives in the) electrolytic solution, the morphology, composition and surface energy of surface coatings are set. In the present study, we evaluated the influence on surface coatings of two solute additives, i.e. hexamethylenetetramine and mannitol, to base solutes silicate and potassium hydroxide. Results from in vitro studies in NaCl demonstrated an improvement in the corrosion resistance. In addition, coatings were obtained by a two-step anodization procedure, firstly anodizing in an electrolyte solution containing sodium fluoride and secondly in an electrolyte solution with hexamethylenetetramine and mannitol, respectively. Results showed that the first layer acts as a protective layer which improves the corrosion resistance in comparison with the samples with a single anodizing step. In conclusion, these coatings are promising candidates to be used in biomedical applications in particular because the components are non-toxic for the body and the rate of degradation of the surface coating is lower than that of pure magnesium.

“…It is apparent that the surface treatment technique can improve the surface energy and wettability of metallic substrates, and is an effective method for enhancing the bonding strength between a metal substrate and a fiber reinforced polymer composite [46]. In addition, the surface treatment can remove the undesirable surface oxides or contaminants on the metallic substrate, and ameliorate the surface composition and microstructure of the metallic substrate [6,47]. This allows the fiber bridging mechanism and mechanical properties of GLAREs to be improved, and moreover, the crack propagation rate at the aluminum-composite interface can be effectively reduced [48,49].…”

Fiber metal laminate (FML) is a hybrid material system that consists of thin metal sheets bonded into a laminate with intermediate thin fiber reinforced composite layers. The aerospace industry has recently increased their use of FMLs due to the considerable weight reduction and consequent benefits for critical load-carrying locations in commercial aircraft, such as upper fuselage skin panels. All FML materials and their processes should be qualified through enough tests and fabrication trials to demonstrate reproducible and reliable design criteria. In particular, proper surface treatment technologies are prerequisite for achieving long-term service capability through the adhesive bonding process. This chapter introduces a brief overview of design concept, material properties and process control methodologies to provide detailed background information with engineering practices and to help ensure stringent quality controls and substantiation of structure integrity. The guidelines and information found in this chapter are meant to be a documentation of current knowledge and an application of sound engineering principles to the FML part development for aerospace usage.

“…The hybridization of fibers in the composite layer of glass-reinforced aluminum (GLARE) laminates using jute/ glass fibers exhibited superior tensile properties. [9] In addition, the researchers studied the effect of the coating of coupling agents like silane, [10] zirconium conversions, [11] phosphating solution [12] on interlaminar fracture toughness of the FML. The metal-composite interfacial bonding was improved when a small amount of CNT [13] or nanosilica [14] was added as filler in adhesives of FML.…”

In this research work, we have investigated the effect of nanoclay fillers in the epoxy adhesive on improving the interfacial adhesion and the mechanical properties of glass-reinforced aluminum laminates. The laminates were prepared with a varying weight percentage of nanoclay fillers (i.e., 3, 4, and 5 wt%) in the epoxy resin using the hand lay-up method. During the tensile test, the laminate's anisotropic nature was investigated using the samples cut in different orientations to the rolling direction (i.e., 0, 45, and 90 ). The flexural, lap shear, and impact tests were conducted as per ASTM standards. After each test, the failure mechanisms of laminates were studied using the scanning electron microscope. The results showed that 3 wt% of nanoclay added in the epoxy enhanced the laminates' overall mechanical properties than other composites. The fiber metal laminates (FML) containing the nano clay more than 3 wt% showed deterioration in the mechanical property due to the improper distribution of nanoclay in the epoxy matrix. The FML's mechanical properties with nano clay filler were compared with other fillers' performance in the previous studies. It was found that the mechanical properties of FML with nano clay filler were more significant than others.
