    • PURPOSE: A friction reducing device and method using lyophilic and lyophobic properties are provided to minimize friction by allowing coagulated liquid to be rolled inside the device. CONSTITUTION: A friction reducing device using lyophilic and lyophobic properties comprises first and second members(140,150) adjacent to each other. Lyophilic areas(110) composed of a lyophilic material are formed on one or more facing surfaces of the first and second members. Lyophobic areas(120) composed of a lyophobic material are formed between the lyophilic areas and repels liquid to the lyophilic areas. The liquid coagulates in the lyophilic areas. When the second member is moved relatively to the first member, the coagulated liquid is moved or rolled in the device.

    • The present invention relates to a quaternary system coating having high-hardness and low-friction characteristics, thus applied to airplanes, conveying machinery, and other tools, and a method for manufacturing the same. Chromium is supplied as a Cr target through a magnetron sputtering using a DC pulse within a single chamber. Titanium and boron are supplied as TiB_2 through a high-voltage impulse magnetron sputtering. Nitrogen is supplied by injecting nitrogen gas inside the chamber. Thereby, when forming a coating film at approximately 200°C which is relatively a low temperature, a crystalline Cr-Ti-B-N coating film can be directly manufactured without any post process such as annealing.
    • 本发明涉及一种具有高硬度和低摩擦特性的四元系涂层,其应用于飞机,输送机械和其它工具,以及其制造方法。 通过使用单个室内的DC脉冲的磁控溅射作为Cr靶提供铬。 钛和硼通过高压脉冲磁控溅射作为TiB_2提供。 通过在室内注入氮气来供给氮气。 因此,当形成相对较低温度的大约200℃的涂膜时,可以直接制造结晶Cr-Ti-B-N涂膜,而不需要任何后处理如退火。
