| Description
| - One of the very important factors, often neglected, determining the final properties of a plasma sprayed deposit is its phase composition. It is well known that spraying of Alumina results usually in formation of other phases than the desired hard ?-phase (corundum) unless stabilizing admixture is added into the feedstock. In this work Chromia was used for stabilization and feedstock powders with 0, 8 and 33 wt % of Chromia, and unalloyed Chromia, were used to produced coatings by WSP(R). Two types of feedstocks were used: fused/crushed and a mixture of Alumina and Chromia powders. The effect of the Chromia content on phase composition, residual stresses, hardness and wear abrasion of coatings was studied. It has been proved by the microanalysis that a certain amount of Cr is transferred into Alumina particles during the %22in-flight%22 reaction of both powders in the plasma jet. Complex %22alloy%22 oxides form where part of Al is replaced by Cr and the ?-phase is partially stabilized.

- Jedním z často zanedbávaných faktorů ovlivňujících konečné vlastnosti plazmových nástřiků je jejich fázové složení. Je dobře známo, že při stříkání oxidu hlinitého dochází k tvorbě jiných fází než k požadované tvrdé korundové fázi alfa pokud není do nanášeného prášku přidána stabilizační přísada. Pro stabilizaci byl v této práci zvolen oxid chromu a použitím prášků s 0, 8 a 33 hm. % Cr2O3 a čistým Cr2O3 byly vyrobeny nástřiky pomocí vodou stabilizovaného proudu plazmatu WSP(R). Byly použity dva typy prášků, stavená a mechanická směs prášků Al2O3 a Cr2O3. Byl studován vliv koncentrace oxidu chromitého na fázové složení, zbytková pnutí, tvrdost a na otěruvzdornost nástřiků. Mikroanalýza prokázala, že během nanášení obou typů prášku dochází k přechodu určitého množství Cr do částic Al2O3. Tvoří se komplexní oxid, kde část Al je nahrazena Cr a částečně stabilizuje fázi alfa. (cs)
