Study of Splat Particle Temperature Distribution in Plasma Spray Forming

摘要

This paper studies the thermal interaction of Ni particle and Al particle setting in the carbon steel surface using ANSYS software by finite element numerical simulation. It highlights the temperature-time change of feature points that are at different locations of flattened particles and substrate, and micro-contact heat transfer of particle and substrate surface is also analyzed. The results help to study residual stress distribution of a splat particle in the plasma spray forming, which further provide an important basis for improving the quality of the coating.
