The sliding conduct is corresponding to a water ski, where great sliding is assured even at very low speeds. This demands the cavities for being of a micro-wedge shape of the necessary accuracy (e.g. flatness 0.6 μm, surface high-quality Ra 0.2 μm), which is attained by Specific laser-structured processing approaches https://www.facebook.com/permalink.php?story_fbid=pfbid0tgzbP3xvRNr7vz9ugJqxZ6qpW5rJYkaQNiedGwxis84bSqzVZmu65mEhkn4EEZaRl&id=61562415773754&__cft__[0]=AZUrPa6046vl1x5Ftd0n16emkDMeojSzj35m7-jdmqDLTpbX-jZAVM_uwJUldY-XHZ04cAZ6vkYT8gm1B3edr4TeP-Apugz1_-4oH5k3it3N097r57Ozvke5N3NZ60v_2AyVWmIqx2dFIvr0wOUjIISc44eGuRP-V0ExBtxAs2yhT7Ru9DNLZcRk2HWmDM0LShzlX5f-MGd7fLEthGwT_Rxd&__tn__=%2CO%2CP-R
