Abstract
1. Способ получения многослойного теплозащитного покрытия на деталях из жаропрочных сплавов, заключающийся в том, что наносят слои покрытия - жаростойкий защитный, содержащий MeCrAlY, и керамический, содержащий ZrO2Y2O3, отличающийся тем, что до нанесения жаростойкого защитного и керамического слоев поверхность детали подвергают алитированию с последующим нанесением связующего слоя покрытия, а после нанесения керамического слоя покрытия осуществляют термообработку детали, причем связующий слой покрытия наносят вакуумно-плазменным способом, жаростойкий и керамический слои покрытия наносят методом газотермического напыления, а при термообработке осуществляют отжиг детали с теплозащитным покрытием в вакууме при температуре 900-1050°С в течение 2-4 ч. ! 2. Способ по п.1, отличающийся тем, что алитирование осуществляют до получения слоя покрытия толщиной 30-50 мкм. ! 3. Способ по п.1, отличающийся тем, что связующий слой покрытия наносят толщиной 20-50 мкм. ! 4. Способ по п.1, отличающийся тем, что жаростойкий слой покрытия наносят толщиной 60-100 мкм. ! 5. Способ по п.1, отличающийся тем, что керамический слой покрытия наносят толщиной 120-240 мкм. ! 6. Способ по п.1, отличающийся тем, что в качестве жаропрочных сплавов используют сплавы содержащие Ni и/или Со. ! 7. Способ по п.1, отличающийся тем, что в качестве Me используют Ni и/или Со. ! 8. Способ по п.1, отличающийся тем, что алитирование осуществляют способом газоциркуляционного осаждения или способом диффузионного насыщения из порошковой смеси или осаждением алюминия с последующим диффузионным отжигом.1. A method of obtaining a multilayer heat-protective coating on parts made of heat-resistant alloys, which consists in applying coating layers - heat-resistant protective, containing MeCrAlY, and ceramic, containing ZrO2Y2O3, characterized in that before applying the heat-resistant protective and ceramic layers, the surface of the part is subjected to alification with subsequent application of the binder coating layer, and after applying the ceramic coating layer, heat treatment of the part is carried out, the binder coating layer being applied in a vacuum-plasma manner, heat-resistant and ceramic coating layers are applied by gas thermal spraying, and during heat treatment annealed parts with heat-protective coating in vacuum at a temperature of 900-1050 ° C for 2-4 hours! 2. The method according to claim 1, characterized in that the alimentation is carried out to obtain a coating layer with a thickness of 30-50 microns. ! 3. The method according to claim 1, characterized in that the binder coating layer is applied with a thickness of 20-50 microns. ! 4. The method according to claim 1, characterized in that the heat-resistant coating layer is applied with a thickness of 60-100 microns. ! 5. The method according to claim 1, characterized in that the ceramic coating layer is applied with a thickness of 120-240 microns. ! 6. The method according to claim 1, characterized in that the alloys containing Ni and / or Co are used as heat-resistant alloys. ! 7. The method according to claim 1, characterized in that as Me use Ni and / or Co. ! 8. The method according to claim 1, characterized in that the alimentation is carried out by the method of gas circulation deposition or by diffusion saturation from a powder mixture or by precipitation of aluminum, followed by diffusion annealing.
