Abstract: Disclosed is a surface layer for a vehicle part. In particular, the surface layer for a vehicle part includes a trivalent dark chrome plating layer; and an organic-inorganic hybrid coating layer forming a chemical bond with the plating layer, and in the organic-inorganic hybrid coating layer, an inorganic nanoceramic oxide is included in an organic synthetic resin base. Therefore, by forming a chemical bond between the trivalent dark chrome plating layer and the organic-inorganic hybrid coating layer, corrosion resistance of the surface layer may not deteriorate in high-temperature environments, thereby overcoming disadvantages of a conventional trivalent dark chrome surface layer. Also disclosed is a method for manufacturing the surface layer for a vehicle part.
