Abstract: There are provided a hydrodynamic bearing assembly and a method of manufacturing the same. The hydrodynamic bearing assembly includes: an oil sealing part formed between a fixed member and a rotating member; and an oil barrier film disposed so as to prevent leakage of oil from the oil sealing part and including a self-assembled monolayer formed on a surface of at least one of the fixed member and the rotating member. The oil barrier film may be easily formed at room temperature and be continuously used for a long period of time without being damaged due to external impacts.

Abstract: There are provided a hydrodynamic bearing assembly and a manufacturing method thereof. The hydrodynamic bearing assembly includes: an oil sealing part formed between a fixed member and a rotating member; and a silicon containing diamond-like-carbon (Si-DLC) or tungsten carbide (W-Carbide) coating layer formed on at least one surface of the fixed member and the rotating member. The silicon containing diamond-like-carbon (Si-DLC) or tungsten carbide (W-Carbide) coating layer is formed on the at least one surface of the fixed member and the rotating member, whereby abrasion of the fixed member and the rotating member due to friction therebetween may be prevented.
