COMPOSITION FOR OBTAINING COATING FOR REDUCING MECHANICAL FAILURES OF HIGH-SPEED ELECTRIC MACHINE ROTOR |
摘要 |
FIELD: chemistry.SUBSTANCE: composition for obtaining coating for reducing mechanical loss of high-speed electric machine rotor relates to hybrid organic-inorganic nanocomposite coatings, capable of reducing mechanical loss of high-speed electric machine rotor in cooling gaseous medium. Composition includes sol with silicate constituent based on tetraethoxysilane or methyltriethoxysilane water-alcohol solution and additionally contains modifying additive in form of compound, possessing pyro- and/or piezoelectric properties with size of particles and their aggregates 50-100 nm, with the following component ratio (wt %): sol with silicate constituent - 96-99; modifying additive - 1-4.EFFECT: application of methyltriethoxysilane in sol composition provides adhesion with stainless steel without high-temperature processing and 11-12 class of surface roughness; application of tourmaline piezoelectric crystals as modifying additive in form of alcohol suspension or crystal powder provides antifriction properties of coating.1 dwg, 3 ex |
