The equipment for temperature gradient sintering by laser beam irradiation which is suitable heat source for heat control and local heating was developed. In this equipment, the laser beam(YAG-laser, 1.06μm, maximum power300W) will be scanned by two oscillating mirrors and will irradiate the specimen setted in the chamber. Temperature profiles in PSZ(Zirconia-stabilized with 3%Yttria) irradiated by laser beam with power 200W were calculated by steady state FEM analysis. The calculated result showed that the temperature of top surface was about 2100K and the temperature gradient between top and bottom surface was about 300K. By means of this laser irradiation condition, PSZ and PSZ/Mo-functionally stepwise gradient material sintered in temperature gradient could be obtained.
