Abstract

The thermal behavior of ceramic powders on the surface of a melting pool during the plasma transferred-arc powder surfacing are theoretically analyzed. The results reveal that for a ceramic powder particle, its experienced heat power from melting pool is much greater than that from arc space during the powder PTA surfacing. It means the heating by the melting pool has taken a much more important part in the particle's thermal behavior than the heating by plasma arc column for a ceramic particle. However, different from the heating by the plasma arc column, the particle's heated power on the 100 A melting pool surface is greater than that on the 200 A melting pool surface.
