| titleOfInvention | METHOD OF OBTAINING MULTICOPHOSIT METAL STRATES FOR THE PROTECTION OF ROTOR ARBOR AND DIAPHRAGMS OF GEOTERM TURBINES |
| abstract | The invention relates to a method of obtaining multi-composite metal layers deposited on rotor shafts, discs and diaphragms forming the geothermal turbines, protecting them against erosion, which results in increased reliability and, implicitly, prolongation of the exploitation period turbines, the method being able to be used for the reshuffling or refurbishing of used components. According to the invention, the method comprises the sorting, dosing and mechanical mixing of metallic elements based on Cr, Ni, Ta, Nb, Mo, W, Si, Al and B in a planetary ball mill to obtain composite powder mixtures, deposition of the first composite layer with a thickness of 100 ... 150 μm, based on microalloyed Cr - Ni powders with small amounts of 3 ... 5% Ta or Ni with 0.5% Fe, max. 0.3% Si, max.0.1% K and 5% B, using a plasma spray deposition process of oxygen at HVOF supersonic velocities, followed by deposition of the second layer, with a thickness between 300 ... 700 μm, made by APS thermal spraying, and may be composed of: a. Micronized Ni-Cr powders which have been obtained by atomization and have the capacity to incorporate 15% WC-based alloy powders - 5Co or WC - 5Mo, b. Mixed toilets with sintered nanostructured products of 100 ... 600 nm from the WC - To which is added micronic powders of 5 ... 10% Co and 5 ... 7% CTa or CNi, c. micronic powder of Al oxide, d. micronic powder of the sinel MgO AlO type, e. micronic powder of mullite type 3A102SiO, f. micronic powder of the 2MgO2AlO5SiO type of cordierite. |
