Microstructural Preparation and the Achievement of a Representative Surface
The complete non-destructive-assessment of engineering surfaces tailored to exhibit engineering properties is, in general, not yet possible. In consequence, sectioning and microstructural examination is widely used as a method of specifying and checking such surfaces, particularly where the thicker coatings have been applied. Microstructural preparation of a sectioned coating is always difficult; although preparation procedures have been devised for many materials, they are usually specific to one manufacturer’s equipment and consumables, and therefore it is difficult to transpose those procedures between equipment. An attempt is being made in the UK to formulate a universal microstructural preparation language which is independent of commercial nomenclature and which will allow the specification of procedures designed to achieve surfaces of the highest integrity.
