ABSTRACT
Laser metal deposition (LMD) is a novel method of fabrication; this deposition process finds extensive application in various engineering fields. There is a pressing requirement for complete functionally graded materials made of metals additively. Understanding the selection of the medium and how chemical structure, phase transition, and mechanical properties relate to one another is crucial. The un-melted component is frequently found when joining different alloys, which could cause structural deviation and defects. Achieving the best joining result requires interaction between LMD systems and as-deposited FGM segments; thus, it’s crucial to optimise the laser processing settings for depositing two or more unique powders together. It is necessary to understand the mechanics in order to understand the characteristics of the created FGM part.
