Abstract:
According to the technology of rapid manufacturing ceramic parts by plasma spray forming, the temperature field distribution of the plasma jet, the method of feeding powder, the energy and momentum transfer between the particle and plasma jet during spraying, and the influence of temperature and velocity property of the particle on forming quality are studied in detail. Meanwhile, the molten state of the particle collected during spraying, and the influence of the flatten state of the particle on the microstructure of the coating are analyzed. The results show that by optimizing the technical parameters, and improving the temperature field distribution of the plasma jet and flight properties of particles, the forming quality can be improved effectively, which is very significant for further widespread application of this technology.
