MULTI COATING LAYER AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed are a multilayered coating layer on which a first coating layer composed of TiN and a second coating layer composed of TiAgN are laminated to be repeatedly alternated and a coating method for the same. A first coating layer (30) and a second coating layer (40) are individually formed at the thickness of 20-300 nm. Ag in whole atoms composing the first coating layer (30) and the second coating layer (40) is 7-20at%.
