Abstract: A brake body according to the present disclosure has a coating layer which contains an iron-based amorphous alloy and is formed on a contact surface at which a friction means rubs against the brake body to generate braking force which the brake body is rotated. The coating layer has a low friction coefficient and thus generates less dust during braking. The coating layer also has high corrosion resistance and wear resistance and may thus guarantee high performance and good price competitiveness when applied to a brake base material produced at low cost.
