	abstract = {7075-T6 aluminium alloys panels were surface conditioned in a titanium colloid suspension, under a variety of different conditions, and subsequently these samples were immersed in a ZnO + H3PO4 coating mixture, and the phosphate coating layers characterized. Morphologies observed by scanning electron microscopy (SEM) reveal that the coating layer consists of two phases, namely an amorphous phase, which is directly bonded to the substrate, and a crystalline phase, in which larger crystal grains grow on top of the amorphous base. Chemical compositions of the coating layers were analysed by X-ray photoelectron spectroscopy (XPS) and by static and imaging secondary ion mass spectroscopy (SIMS). It is found that the details of the surface conditioning affect the final coating, both in terms of morphology and chemical composition. For example, larger amounts of Zn and P are detected in coatings for which the initial conditioning is done at 40 degrees C, compared with room temperature; a similar statement can be made for surfaces which are water rinsed after the Ti pretreatment, compared with those which are not water rinsed prior to the coating treatment.},

	abstract = {A zinc phosphate coating process on 7075-T6 aluminum alloy has been significantly improved through a combined approach of titanium colloid pretreatment, pH level adjustment, fluoride additive and ZnO/H3PO4 ratio adjustment. In particular, optimum phosphate coatings were formed in coating baths with a ZnO/H3PO4 ratio of 0.205 and 0.256. Coating morphology studied by SEM reveals that the adjustment in the coating procedure produces an improved crystalline coating layer with high coverage and small grain size. For coatings formed in a bath with a ratio of 0.205, the coverage of the crystalline patches on top of the amorphous coating base is almost complete. The chemical composition of the coating layers has been characterized by XPS and SIMS. The crystalline and amorphous coating phases formed in the bath with a ratio of 0.205 were found to have compositions given schematically as Zn-x(PO4) and ZnxAly(PO4), respectively. In contrast, neither coating phase formed in the bath with a ratio of 0.256 shows the presence of Al.},

	abstract = {X-ray photoelectron spectroscopy (XPS), combined with scanning electron microscopy (SEM), weight loss tests and atomic absorption spectroscopy (AAS), has been applied to investigate the corrosion protection properties of zinc phosphate when coated on 7075-T6 aluminium alloy. XPS is consistent with the coating process leading to both physically adsorbed and chemically absorbed zinc. The former is washed away by ultrasonic washing, but the chemically absorbed component, identified as ZnO(x), is incorporated into the aluminium oxide layer. This layer helps suppress the dissolution of aluminium during the corrosion process.},
