The sliding behaviour is similar to a water ski, where excellent sliding is assured even at minimal speeds. This needs the cavities to get of the micro-wedge form of the required accuracy (e.g. flatness 0.six μm, surface excellent Ra 0.two μm), which is realized by Specific laser-structured processing strategies �?a https://www.quora.com/profile/Trevor-Flatcher-2/Advantages-and-Challenges-of-Silicon-Carbide-Specialty-Ceramics-Macrocosm-Materials-Company-Overview-Founded-in-2016
