Research on Plasma Spray Particle Impact Matrix Process Simulation

摘要

Plasma spraying rapid making of functionally graded mold is an effective preparation method. In this paper, finite element method simulation of the plasma spray process a single droplet deformation and matrix effects in the process. Studies have shown that: speed large solidification time is short, more conducive to the formation of the coating; speed large residual thermal stress is small; preheat temperatures are high, the particle flattening effect, The research results will provide theoretic basis for improving spraying coating quality.
