Abstract: The concept of ||Functionally Graded Materials||, FGM, was introduced in 1980s for the development of reliable thermal shock resistant components for high temperature applications. Later on biomimetic approaches were included, to arrive at multifunctional, multiscale FGM|s for numerous applications, including abrasion resistant materials and materials for implants. The paper briefly reviews the past achievements and highlights future trends in multi-scale graded materials science and technology, with the aim at utilisation of bio-inspired methods in design and fabrication strategy. Examples are given for systems with hierarchically graded porosity for application in hard tissue implants and in diesel engine filters, respectively.
Keywords: bio-inspired design; diesel engines; engine filters; hard tissue implants; TBC; thermal barrier coatings; fuel cells; functionally graded materials; FGM.
