Electrical discharge coating (EDC) process is applied for preparation of hard and wear-resistant coating by using green compact tool of Cu+MoS₂+WS₂+hBN powder. XRD analysis suggests that the coating morphologies comprises of hard and soft phases. Further, EDS line scan along cross-section reveals that concentration of coating elements increases from workpiece to coating surface direction. FESEM results indicate that applied coatings exhibit a hierarchical rough structure. Due to the hierarchical coating structure, the water contact angle (WCA) is raised to a super-hydrophobic state (152.2°). The developed coatings also exhibit higher microhardness and low specific wear rates than substrate. It is aimed that the enhancement in mechanical durability of superhydrophobic surfaces will be beneficial for the extensive application of a superhydrophobic coating.

通过使用绿色紧凑型工具Cu + MoS ₂ + WS _2将放电涂层（EDC）工艺用于制备硬质耐磨涂层+ hBN粉末。XRD分析表明涂层形态包括硬相和软相。此外，沿横截面的EDS线扫描显示涂层元素的浓度从工件到涂层表面方向逐渐增加。FESEM结果表明，所施加的涂层表现出分层的粗糙结构。由于分层的涂层结构，水接触角（WCA）升高至超疏水状态（152.2°）。与基材相比，已开发的涂层还具有更高的显微硬度和较低的比磨损率。目的是提高超疏水性表面的机械耐久性将有益于超疏水性涂层的广泛应用。
