Abstract
The efficiency of application of an extension in plasma spraying of coatings from quasi-crystalline alloy Al-Cu-Fe was studied. It was established that the extension allows increasing the amount of the icosahedral phase in a coating by improving the heating conditions and lowering the degree of oxidation of a spraying material.
