Abstract: Disclosed is a coating layer penetrable by radio wave and having a metallic luster. The coating layer includes a resin layer as an outmost layer to an exterior or front, a metallic texture layer formed on a rear side of the resin layer and comprising a optical film layer including metal oxides having different refractive indexes, and a germanium (Ge) layer to reflect light and a reflection layer formed on the rear side of the metallic texture layer.

Abstract: Disclosed herein are a metal texture coating for transmitting an electric wave and a manufacturing method thereof The metal texture coating for transmitting an electric wave includes: a transparent resin film; a metal texture layer deposited on any one of both surfaces of the resin film; and a chromium oxide layer deposited on the metal texture layer so as to transmit the electric wave therethrough and protect the metal texture layer.

Abstract: Disclosed is a radio wave penetration-type multilayer optical coating. The coating includes: a transparent first resin layer; an optical coating with a multilayer structure formed by alternately forming TiO2 and SiO2 on the first resin layer; and an opaque second resin layer formed on the optical coating.

Abstract: Disclosed are a coating layer of a zirconium composite material which can be applied to a friction portion and the like of a power train part of a vehicle, and a method of forming the coating layer. In particular, the coating layer of a zirconium composite material includes a ZrCuAlMo layer that is an intermediate layer for close contact force and a ZrCuAlMoN layer that is a functional layer for a low friction coefficient and durability and the ZrCuAlMo layer and ZrCuAlMoN layer are sequentially laminated on a surface of a base material to reduce friction of the friction portion. Accordingly, wear resistance, durability life, and the like may be improved, close contact force with the base material may be improved, and impact resistance and the like may be enhanced.

Abstract: Disclosed are a transceiving surface-treated metallic member disposed within a transmission path of a radar, and a method of manufacturing the transceiving surface-treated metallic member. The surface-treated metallic member in the invention provides a more secure transception property within the transmission path of the radar, particularly when it is applied as a smart cruise control (SCC) cover, has an aesthetic appearance, and is manufactured at reduced cost.

Abstract: Disclosed are an RF equipment protection device and a mounting method for same. The RF equipment protection device of the present invention includes a main body with an open front end and an open rear end to accommodate RF equipment having an input/output connector, a first cover which is arranged to cover the front end of the main body, and having a connector hole for the passage of the front end side connector of the RF equipment, and a second cover which is arranged to cover the rear end of the main body, and has a connector hole for the passage of the rear end side connector of the RF equipment. The RF equipment protection device of the present invention is provided with a housing for accommodating the RF equipment, advantageously protecting the RF equipment in a stable manner and reducing manufacturing costs.
