Corrosion resistance of cold-sprayed Ta coatings in very aggressive conditions / Bolelli, Giovanni; Lusvarghi, Luca; H., Koivuluoto; P., Vuoristo; F., Casadei. - In: SURFACE & COATINGS TECHNOLOGY. - ISSN 0257-8972. - STAMPA. - 205:(2010), pp. 1103-1107. [10.1016/j.surfcoat.2010.02.052]
Abstract:
This study deals with the corrosion behaviour of high-pressure cold-sprayed Ta coatings, compared with Tabulk material and inert-atmosphere plasma-sprayed Ta coatings. Electrochemical polarization andelectrochemical impedance spectroscopy measurements are carried out in 1 M KOH solution; immersiontests are performed in 1 wt.% HF solution, and the resistance to high-temperature oxidation and molten saltattack is evaluated by hot corrosion tests. Moreover, the effect of substrate material (steel, Al and Cu) on thecoating formation is investigated using FESEM.
