High temperature resistance improvement (500 °C) and corrosion resistance in salt spray test (47 °C) at different time intervals with and without surface modified with Ni coating of SmCo alloy was carried out. The results showed that mass gain of Ni coated sample is far less then uncoated sample when oxidized at 500 °C for 300h and the loss of magnetic properties for coated magnets were also almost...
Bioinspired mushroom-shaped microfiber arrayed surface demonstrates superhydrophobicity. Such a textured surface is fabricated by an electrohydrodynamic (EHD)-based structuring process, which is a combination of hot embossing, electrically induced growing and electrowetting. First, an ordinary micropillar array is prestructured on a conductive substrate through the hot embossing process. Second, another...
