Effects of Processing Parameters on Functionally Graded Materials for Industrial Components Repair

The production of functionally graded materials (FGM) is an option for various industrial sectors and a solution for many engineering applications. FGMs are a class of materials that gradually change composition and structure, and whose properties vary throughout the material, depending on the spatial position in the material bulk structure. This article presents FGMs briefly as new materials for components repair using the direct laser deposition technique, emphasizing processing parameters and process optimization.
