Abstract: A pipe according to the present disclosure comprises: a hollow tube body in which fluids of different temperatures pass through the inside and outside thereof; and a coating layer which is provided on an external surface of the hollow tube body, and which has an alloy comprising an amorphous phase, wherein the alloy comprises Fe, and comprises at least one or more first component selected from the group consisting of Cr, Mo and Co, and at least one or more second component selected from the group consisting of B, C, Si and Nb.

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.

Abstract: According to an aspect of the present disclosure, a heat-resistant coating composition includes: an inorganic filler which is iron (Fe)-based amorphous alloy powder having an amorphous phase and an average particle diameter of 0.5 ?m to 15 ?m; and a binder, where the coefficient of thermal expansion of the inorganic filler is lower than the coefficient of thermal expansion of the binder.

Abstract: Disclosed is a golf club and a method of manufacturing the same, whereby an Fe-based amorphous alloy layer is coated on a surface of a base part of a clubface provided on a side of a clubhead to maintain an amorphous structure after coating, thus ensuring that a repulsive force, durability, surface hardness, and the like of the clubface are improved. The golf club includes: a clubhead; and a shaft connected to the clubhead, wherein the clubhead includes a clubface provided on a side thereof, and the clubface includes: a base part; and a coating layer provided on a surface of the base part and including an Fe-based amorphous alloy.
