Professional paper shows the general characteristics of graded materials, their previous industrial use and potential use of graded materials in the future.
Introduction Graded materials (FGM - Functionally Graded Materials) are in intensive use for last two decades.
The largest groups of graded materials are as follows: - bioactive graded materials, - tool steel with C, V, Cr and Ti gradients, - materials with self-lubricating ability, - graded materials with high temperature resistant surface layer. 2.
Properties of functionally graded materials Graded materials are very innovative product in the field of technology.
