摘要： Disclosed is a surface treatment method for producing a coating layer, which improves surface properties (e.g., low friction wear-resistance) of the coating layer at high temperature. The surface treatment method controls a process pressure during the formation of a coating layer to form a fine surface morphology with increased silver (Ag) content. The surface treatment method includes: heating a coated material in a chamber; removing foreign substances from the surface of the heated, coated material; forming a buffer layer on the surface of the coated material; and forming a coating layer on the buffer layer, wherein the process pressure is controlled during the formation of the coating layer to improve the surface properties at high temperatures.
