Effect of Surface Periodic Structures for Bi-directional Rotation on Water Lubrication Properties of SiC

In order to improve the lubrication properties of silicon carbide (SiC) in water, symmetrically spiral periodic structures for bi-directional rotation were intermittently and alternately produced on the surface. These periodic structures of submicron size develope in a self-organized fashion on a su...
