Abstract
The present disclosure provides an improvement to razor blade coating by a physical vapor deposition method, by forming a hard coating layer as a thin coating layer in which chromium boride, which is a nanocrystalline structure having high hardness, is dispersed in an amorphous mixture of chromium and boron, thereby improving the strength and hardness of the thin coating layer and securing the bonding force by chromium in the amorphous mixture between the hard coating layer and a blade substrate on which an edge of the razor blade is formed.
