Název v původním jazyce

Dependence of the Stabilization of -Alumina on the Spray Process

Popis výsledku v původním jazyce

A phase change from alpha-alumina (corundum) in the feedstock powder to predominantly other alumina phases, such as -alumina in the coating normally takes place, as a result of the spray process. It is expected that the prevention of this phase transformation will significantly improve the mechanical, electrical, and other properties of thermally sprayed alumina coatings. The results regarding the possibility of stabilization of ?-alumina through addition of chromia published in the literature are ambiguous. In this work, stabilization using different spray processes (water-stabilized plasma (WSP), gas-stabilized plasma (APS), and high velocity oxy fuel spray (HVOF)) was studied. Mechanical mixtures of alumina and chromia were used, as were prealloyedpowders consisting of solid solutions. The investigations focused on mechanical mixtures with both APS and WSP and on prealloyed powders with WSP.
