“…The stable connection and lack of harmful defects cause FSW joints of very high corrosion resistance. As it was demonstrated, corrosion resistance of FSW materials depends on several process parameters, such as traveling speed or tool geometry . However, there are some inconsistencies regarding the corrosion resistance of joints compared to the initial states of material to be joint materials.…”

“…In the welding of aluminum alloys by FSW process, it was found that the corrosion properties of welded joints are markedly affected by the welding parameters such as rotational and welding speeds. The effect of the FSW process parameters on the corrosion behavior of FS welded aluminum joints were studied by many workers [9][10][11]. Nam et al [9] investigated the effect of welding speed on the corrosion properties of AA6061 FSW welded joints using potentiodynamic polarization test.…”

T HE aim of the present work is to study the effect of rotation and welding speeds as well as the T4 and T6 post-weld heat treatments (PWHT) on the corrosion behavior of AA6061-O aluminum plates joined using friction stir welding (FSW). The corrosion properties of welded joints were studied by Potentiodynamic polarization and Immersion tests. The results showed that both T4 and T6 PWHT improves the corrosion resistance of stirred zones compared to base alloy. However, joints of T4 showed lower corrosion resistance compared to T6. Increasing welding speed or reducing rotation speed increased the corrosion resistance of joints.

The corrosion resistance of MoNb/AlNd/MoNb film during different sputter conditions was studied for G6 rotating target sputter equipment. The results show that with the increase of sputter power and the increase of the thickness, top MoNb tends to form coarse columnar crystals, and the corrosion resistance of the metal thin films, at first, increases and then decreases with the increase of sputter power and metal thickness. As the sputter temperature increases, top MoNb tends to form coarse grains while the corrosion resistance of the film is poor. The result also release that with the increase of the target speed, top MoNb film becomes loose so that it is difficult to play a protective role because of its poor corrosion resistance ability. Under the same conditions, the sputter of the planar target film is denser; as a result, the top MoNb layer can protect the inner AlNd layer from corrosion.
