Abstract
Corrosion resistance of detonation and plasma coatings of AlCuFe base powders alloyed with scandium, chromium and a set of elements Ti, Cr and Si in 0.1 n KOH solution, 0.1 n HCl solution and synthetic sea water was studied by the potentiostatic method. Dependence of electrochemical properties (potential and electrochemical rate of corrosion) of the coatings upon their spraying method, compositions and quasi-crystalline phase content was determined.
Keywords: thermal spray coatings, quasi-crystalline phase, Al–Cu–Fe system alloy, corrosion properties
