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:
