METHOD OF MANUFACTURING PARTS FROM CERAMIC OF COMPOSITES Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: method involves applying ceramic or composite layer onto working surface by gas-thermal spraying and simultaneously supplying cooling agent to the zone of contact between working surface and material sprayed, with one or more components of material sprayed being used as cooling agents or their mixture with other cooling agents. Separation of finished part from base is effectuated by providing base with spiral groove, where flexible member is positioned, with at least one cross size of flexible member being equal to spiral groove coil spacing. Upon application of layer, base is separated from finished part and flexible member is removed. If base makes a portion of part to be manufactured, spiral member is positioned on base and fixed to it prior to spraying ceramic or composite layer. Additional cooling of part is provided by supplying air-gas mixture to the surface outside spraying zone. Intensity of additional cooling process is controlled by varying rate of gas flow passed through cooled liquid. EFFECT: increased efficiency of method and high quality of parts. 4 cl, 3 dwg
