dcterms:description
Byl testován otěr v suspenzi na extrémně tlusté samonosné vrstvě plazmového nástřiku. Tloušťka nástřiku také umožnila sledovat otěr ve směru nástřiku a ve směru kolmém, tedy na řezu. Vzorky oxidu hlinitého byly rovněž připraveny nástřikem s osou skloněnou vůči podložce pod různými úhly. Tyto vzorky byly testovány normalizovaným přístupem a srovnávány. Výsledky ukazují, že odklon plazmatronu vede k poklesu otěruvzdornosti - optimální konfigurace je kolmá. Nástřik má na příčném řezu lepší otěruvzdornost než na povrchu. Slurry testing of extremely thick plasma sprayed alumina freestanding layer is reported. The thickness of coating allows us to perform the test in-plane and also perpendicularly – i.e. at a cross sectional orientation. Alumina plasma coatings were also sprayed using setup with deflection between the plasma torch axis and the substrate surface. Those coatings were tested at standardized conditions and compared together. The results show that the torch deflection decreases the wear resistance. Optimal configuration is the perpendicular one. The extremely thick coating produced at this configuration is very homogeneous along the depth and its wear resistance is constant. This coating exhibits better wear resistance when tested at cross sectional orientation. Other properties like microhardness are reported as well but the main attention is paid for slurry testing.
