The effects of vertical gravity fields on the structural characteristics of electrodeposited Ni foils were investigated in a centrifuge. Analysis by atomic force microscopy (AFM) shows that the surface roughness of Ni foils reduces from 37.6nm to 8.1nm with the increase of gravity coefficient (G) from 1 to 354. Furthermore, the roughness of Ni foils deposited at G=62 evolves much more slowly than...
The influence of the surface roughness of Mg alloys on the electrical properties and corrosion resistance of oxide layers obtained by plasma electrolytic oxidation (PEO) were studied. The leakage current in the insulating oxide layer was enhanced by increasing the surface roughness, which is a favorable characteristic for the material when applied to hand-held electronic devices. The variation of...
