Snapshots of Hot Surface and Cold Droplet Interaction at 3 Milliseconds (IMAGE)
Caption
At high temperatures, ceramics are susceptible to thermal-shock fractures caused by rapid temperature-changing events, such as cold water droplet contact with hot surfaces. In a novel interdisciplinary approach, engineers at the University of New Mexico report in AIP Advances the use of a cheap, simple, water-repelling coating to prevent thermal shock in ceramics. These are snapshots of hot surface and cold droplet interaction at 3 milliseconds at 300 degrees Celsius: (a) on as-received alumina ceramics and (b) on an engineered hydrophobic surface.
