Functionally graded materials (FGM) have a wide range of applications and domestic R&D enthusiasm is high

with the deepening of research, the preparation processes for functionally graded materials have also become more diversified, including self-propagating high-temperature synthesis (shs), dry spraying + temperature gradient sintering, centrifugal casting, plasma spraying, direct liquid film formation, thin film infiltration molding, particle co-sedimentation, vapor deposition, additive manufacturing (am) and other processes. functionally graded materials have spatially…
