Fabrication of TiO2 Films by Anodisation of Ti-Foils in Oxalic Acid
… Different anodisation parameters, such as anodising voltage, electrolyte concentration and anodising time, have been investigated in order to explore their effects on the photocatalytic performance of the films. Regarding the effect of anodisation voltage, GAXRD analysis showed that anatase …

Investigation into the surface modification of Ti-6Al-4V to facilitate antimicrobial ionic silver integration for use in implantable orthopaedic devices
… ICP-MS. This study was limited to the use of two anodising electrolytes (i.e. 0.5M H2SO4 and 2.1M H3PO4) and altering the AgNO3 concentration (0.05 - 5.0M) and Ag implantation dosage (0.4 - 1.2x1017 ions/cm2 ), where applicable to the method. Results from the Ag ion exchanged samples showed that, …

Laser and electron beam treatments for corrosion protection of friction stir welds in aerospace alloys
… necessary is the removal of paint and anodising layers from aerospace alloys. Laser paint removal was assessed and designed to remove these layers with only an oxide remaining, which welded to produce high quality welds. The post-weld treatment was essential to increase the corrosion …

Adhesive properties of thermoset fibre metal laminates
… surface treatments such as alodining, etching, anodising, silane treatments and combinations thereof were investigated. The effect of resin and the inclusion of a film adhesive were also investigated. The silane treatments were identified as the chemical treatments that provided the best …

In vitro bioactivities of anodised titanium in mixtrue of B-Glycerophosphate and calcium acetate for biomedical application
… M β-GP + 0.2 M CA, 0.04 M β-GP + 0.04 M CA) , anodising time (5-10 mins), agitation speed (300-1500 rpm), ultrasonic amplitude (20-60 μm) and bath temperature (4-100 °C) were varied to investigate the impact on the surface properties of titanium. The results showed that surface of the titanium …

The colouring, sealing and abrasion resistance of anodic oxide coatings
… is dependent upon the control of the anodising, colouring and sealing processes. The quality of the anodic oxide film is determined by assessment tests. The use of a nitric acid ‘predip’ on soft films was shown to dissolve a soft outerlayer. A new admittance test was devised in which …

Tribological characteristics of coatings on aluminium and its alloys
Hard anodising on aluminium and its alloys has been widely practised for many years in order to improve the resistance of the otherwise poor wear characteristics of aluminium. In recent years there has been an increasing interest in other treatments and coatings, on both aluminium and other base …
