The present disclosure provides a sealing device and an in-wheel motor including the sealing device. The in-wheel motor includes a stator, a rotor rotatably disposed with respect to the stator, an annular inner seal connected to the stator and spaced apart from the rotor by a predetermined gap so as to be disposed between the stator and the rotor, and an annular slinger coupled to an end portion of the rotor, wherein the annular inner seal seals between the slinger and the in-wheel motor.

Disclosed is a piston ring for engine that includes chromium (Cr) coating layer coated on the surface of a base material of the piston ring of an engine; a chromium nitride (CrN) coating layer; and a silicon-incorporated diamond-like carbon (Si-DLC) coating layer, which is formed on the CrN coating layer, and contains Si component of about 3&#x2dc;10 at %, and a method for manufacturing thereof.

Piston ring for engine

The present invention provides a valve lifter, including a buffer layer, a Me diamond-like carbon layer having a thickness of 0.3&#x2dc;0.6 &#x3bc;m, and a diamond-like carbon layer having a thickness of 1&#x2dc;1.5 &#x3bc;m and a SP3 bonding fraction of 60&#x2dc;70%, which are sequentially formed on a base body which is subjected to carbonitriding treatment. The valve lifter can exhibit superior low-friction characteristics and wear resistance.

Valve lifter and surface treatment method thereof

The present invention provides a metallic bipolar plate for a fuel cell and a method for forming a surface layer of the same, in which the surface layer is formed in such a manner that a plasma nitridation process is performed on the surface of a stainless steel base material to form a nitrogen implanted layer, and oxidation and reduction processes are performed on the surface of the nitrogen implanted layer to form a FeOsurface oxidation layer thereon, thus improving conductivity and corrosion resistance.
