Surface Analysis FacilitiesWhat is surface analysis?Surface analysis involves the determination of the chemical distribution and structural composition of the outermost layers of solid surfaces. In particular, surface analysis is a sensitive method of performing chemical analysis on very small quantities of material in the first 5-10 atomic layers of the solid surface. Surface analytical techniques are also capable of measuring variations in composition with depth. The nature of the surface layers control many technologically important processes including corrosion, catalysis, adhesion, friction and wear; moreover, surface layers influence the properties of a wide range of materials such as metals, ceramics, polymers, composites, alloys, textiles, biomaterials and glass. Why use surface analysis?Materials problems cost Australian industry millions of dollars per year. Many of these problems have a common feature: they are surface dependent. Therefore, they can be solved using surface analysis techniques. The ability to accurately characterise surfaces is essential in terms of improved quality control, process or product problem solving and the research and development of new products and processes. Materials characterisation through surface analysis provides unique information about the composition of the uppermost atomic layers of solid materials, in may cases in a non-destructive manner. In addition to providing spatial (3D) elemental and chemical images at or near the surface, surface analysis can answer questions concerning the identification and concentration of surface species and the actual special distribution can be examined. Virtually all vacuum-compatible solid materials – including fibres and powder – and any species deposited onto a solid surface can be analysed. Minimal sample preparation is required. The Sydney Surface Analysis FacilityThe Sydney Surface Analysis Facility (SSAF) at the University of New South Wales is a key materials characterisation centre for industry, universities, Government and R & D laboratories. Established in 1990, SSAF has the most comprehensive range of specialised surface analysis instrumentation and expertise dedicated to contract analysis and research in Australia. SSAF uses state of the art scientific techniques including:
ApplicationsThe typical applications of surface analysis are analysis of stains and contaminants, particle characterisation, forensic studies and environmental testing. In particular, SSAF has provided solutions to problems in:
