Al foam is lightweight with superior shock-absorbing properties but has low tensile and bending strengths. This has spurred efforts to form composites of Al foam with dense materials. In this study, we examined the possibility of fabricating composite structures of Al foam and dense steel with strong metal bonding by employing friction welding. The use of friction welding is expected to facilitate the fabrication of Al foam/ dense steel composites by a simple process with low environmental impact. It is shown that this procedure is capable of fabricating an Al foam/ dense steel composite in which the Al foam completely fills the hollow in the dense steel. An FeAl intermetallic compound (IMC) layer with a thickness on the order of 10 µm was found throughout almost the entire interface between the Al foam and the dense steel. Therefore, it is shown that an Al foam/dense steel composite with strong metal bonding can be fabricated.

“…1,2 Traditionally in Europe, aluminium alloys have undergone a chromatecontaining conversion coating or chromic acid anodizing pretreatment to improve corrosion resistance and to assist coating or bond durability. 3 However, processes using hexavalent chromium species are now undesirable in manufacturing due to the high disposal costs and increasing legislation related to their toxicity.…”

The influence of ambient atmospheric exposure on the chemistry of the magnetron-sputtered aluminium surface has been characterized as hydroxyl incorporation to the oxide surface and concurrent adsorption of airborne carbonaceous contamination. Here, the consequence of these changes in oxide surface chemistry upon the adsorption of stearic acid from solution is investigated. Water contact angle and polarization modulation infrared refection-absorption spectroscopy (PM-IRRAS) reveal a strong dependence of stearic acid monolayer order upon ambient exposure time prior to assembly. It is proposed that hydroxyl formation in the ambient atmosphere increases the stearic acid adsorption density and thus the selfassembled monolayer (SAM) order, whereas airborne carbonaceous material blocks these adsorption sites and introduces disorder in the monolayers through a decrease in adsorption density.Monolayer adsorption has been correlated with the aluminium oxide surface chemistry. It is proposed that this phenomenon represents an explanation for the irreproducible results often reported for assembly on metal oxide substrates. Furthermore, it indicates that in this broad class of material surfaces assembly can be used as a means of estimating the reactivity of surfaces with respect to organic overlayers such as paints and adhesives. Removal of adsorbed carbonaceous material from the aluminium surface using an oxygen plasma resulted in a significantly increased order of the stearic acid monolayer, as assessed by water contact angle. This observation is rationalized as the removal of carbonaceous material blocking surface adsorption sites by the plasma, but retention of the underlying hydroxyl functionality. This is predicted to have important implications in the preparation of aluminium for painting and adhesive bonding.

Lap Joint of A5083 Aluminum Alloy and SS400 Steel by Friction Stir Welding

A lap joint of A5083 aluminum alloy and SS400 steel was produced by Friction Stir Welding (FSW) using the various process parameters such as rotational speed, traverse speed and pin depth. The variations of welding parameters produced various characteristic interfaces and had conspicuous influences on the joint properties. Increasing the rotational speed decreased the shear load of the joint due to producing a thick FeAl 3 intermetallic compound (IMC) at the interface. When traverse speed increased, the shear load increased because IMC thickness at the interface decreased, however, when the speed was so high, an incomplete interface was formed. Increasing the pin depth produced a thick FeAl 3 IMC phase and an incomplete interface that directly deteriorated the shear load of the joint.
