Abstract:
An exhaust manifold may include a main body provided with a plurality of branching passages communicating with a vehicle engine and provided with a single passage communicating with an exhaust canister, the branching passages merging with the single passage; and a coating layer coated on an internal surface of the main body forming the branching passages and the single passage, the coating layer including an aerogel.
Abstract:
Disclosed is a thermal insulation coating composition including: a polymer resin; an aerogel; and an amphiphilic compound including specific functional groups and having a weight average molecular weight of about 200 to about 5000. A thermal insulation coating layer obtained from the thermal insulation coating composition is also provided.
Abstract:
Provided is a surface treatment method, including: preparing a composite comprising chromium (Cr) of about 95 to 98 atomic percents and copper (Cu) of about 2 to 5 atomic percents with respect to the total number of atoms in the composite; and forming a coating layer comprising Cr of about 30 to 40 atomic, Cu of about 2 to 5 atomic percents, with respect to the total number of atoms of the coating layer, and N constituting the balance of the atoms of the coating layer, by sputtering from the composite in a nitrogen-containing atmospheric gas. Further, provided is a vehicle part, surface of which is treated with the same method.
Abstract:
Disclosed are a coating layer including pores for thermal insulation and a method of preparing the same. As such, the coating layer may secure low thermal conductivity, low volume heat capacity and improved durability, such that the coating layer can be applied to an internal combustion engine.
