Corrosion protection of Mg/Al alloys by thermal sprayed aluminium coatings Pardo Gutiérrez Del Cid, Ángel Casajús, P. Mohedano Sánchez, Marta Coy, A.E. Viejo, F. Torres, B. Matykina, Endzhe The protective features of thermal sprayed Al-coatings applied on AZ31, AZ80 and AZ91D magnesium/aluminium alloys were evaluated in 3.5 wt.% NaCl solution by electrochemical and gravimetric measurements. The changes in the morphology and corrosion behaviour of the Al-coatings induced by a cold-pressing post-treatment were also examined. The specimens were characterized by scanning electron microscopy, energy dispersive X-ray analysis and low-angle X-ray diffraction. The as-sprayed Al-coatings revealed a high degree of porosity and poor corrosion protection, which resulted in galvanic acceleration of the corrosion of the magnesium substrates. The application of a cold-pressing post-treatment produced more compact Al-coatings with better bonding at the substrate/coating interface and higher corrosion resistance regardless of the nature of the magnesium alloy. 2024-07-24T09:26:14Z 2024-07-24T09:26:14Z 2024-07-24T09:26:14Z 2009-05-15 journal article https://hdl.handle.net/20.500.14352/107104 XXXX-XXXX 10.1016/j.apsusc.2009.03.022 eng The authors wish to thank the MCYT for the financial support given to this work (Project MAT2006-13179-C02-01-02).
