Description
  • Plasma sprayed aluminum oxide-based coatings (Al2O3) are mainly used as a wear resistant surface covers in mechanical applications. Previous studies have shown that abrasion wear resistance of these coatings can be significantly improved by applying a sealing treatment. It was reported that this improvement is mainly due to microstructural toughening which takes place via the sealing process. Therefore, this study was conducted in order to determine the influence of the microstructural characteristics governed by the spray system settings and epoxy sealing on the wear resistance of these coatings. Unsealed and epoxy resin sealed plasma sprayed specimens prepared from alumina as well as alumina-13% titania were studied. Abrasion wear resistance of these coatings was evaluated employing the standard slurry abrasion response (SAR) and the standard dry sand rubber wheel (DSRW) abrasion tests.

  • Plazmové nástřiky mohou být zlepšeny z hlediska otěruvzdornosti dodatečnou impregnací epoxydovou pryskyřicí. Pro aplikace za nízkých teplot se takto zvýší houževnatost nástřiků. V článku je popsáno zkoušení otěruvzdornosti nástřiků na bázi oxidu hlinitého (Al2O3) v podobě bez impregnace a s ní. Vzorky byly testovány za sucha metodou DSRW a za mokra metodou SAR. Do rozboru výsledků byly zahrnuty i pórovitost, mikrotvrdost a drsnost povrchu vzorků. Bylo prokázáno, že impregnace zlepšuje otěruvzdornost nástřiků při obou testech. (cs)
