Practical Surface and Interface Analysis of Industrial Coatings

Understanding the surfaces/interfaces of a material and its interaction with the surrounding environment are important drivers steering modern technological applications and innovations. While it defines the boundary between the bulk of a material and its surrounding environment, it is important to realise that surface atoms have fewer nearest neighbours. It will be in a different physical and chemical environment from that in the bulk. The surface behaviour and reactivity will determine how well the material performs in its intended function and usage. This will be of particular interests for materials structured at the nanoscale. As the physical dimensions of a material decreases from 1mm to 100nm and eventually towards the atomic scale, more of atoms of the material are at the surface rather than in the bulk. It is thus important that the surface properties of materials used in todays’ world are well understood. Analytical techniques that will enable surface chemical and physical states to be probed and clearly distinguish it from the underlying bulk are thus required.

This course will provide a primer into understanding surfaces of materials and its reactivity. Together, with the concepts of selectivity and sensitivity, the principle and application of NUS analytical tools such as XPS, AES, SIMS, AFM, TEM/EDX/EELS, FIB/SEM will be presented with specific references to Surface finishing/engineering and allied industries. Besides, other traditional bulk analytical techniques are also briefly described & complimented with references to scientific research and industrial applications. These advanced analytical tools and specialized methodologies have been providing facility to leading edge research labs and regional manufacturers to link composition , structure, morphology, roughness, hardness and adherence with defect reduction, yield improvement and optimum performance enhancement. It is indispensable in material & process research, process development, defect free manufacturing and product reliability.
