Summary

Functionally graded materials are materials that comprise a spatial gradation in structure and/or composition, tailored for a specific performance or function. They are most beneficial when a component requires diverse and sometimes seemingly contradictory properties. Examples include coated or cladded materials that retain the desired properties of the bulk substrate while acquiring new desired surface properties. The author describes several examples of applications and why functionally grade materials are used. Designers need to consider functionally graded materials whenever they need properties not attained in a single material.
