The sliding behaviour is corresponding to a water ski, where superior sliding is assured even at minimal speeds. This needs the cavities being of a micro-wedge form of the necessary precision (e.g. flatness 0.six μm, surface high-quality Ra 0.two μm), which is reached by Specific laser-structured processing tactics �?a neodymium https://x.com/hongyuxin20/status/1818178462718501187
