FIELD: machine engineering.
SUBSTANCE: ceramic material part comprises a part forming a base and a part forming a wall. The base is made of ceramic material of low porosity, and the wall contains a low-porosity shell and a core inside the shell. The porosity of the core is greater than the porosity of the base increasing with distance from the base. The base and the wall are obtained by ceramic powder sintering. The wall is formed in a powder-containing vessel by selectively sintering the powder by successive layers by a laser beam or an electron beam.
EFFECT: reduced level of stresses in the part base.
