Embodiment Construction

[0053]A method of manufacturing the friction member 10 of a bicycle brake as one example of a bicycle component will now be described. As shown in FIG. 1( a ), the manufacturing method of the friction member 10 includes forming a powder compact CB including at least three kinds of powders P1 , P2 and P3 , and subjecting the powder compact CB to combustion synthesis. Combustion synthesis can be called self-propagating high-temperature synthesis. The at least three powders P1, P2 and P3 are reactants in the combustion synthesis. The friction member 10 containing an intermetallic compound (for example, a Cu—Ti-based intermetallic compound) was manufactured by combustion synthesis. In the present embodiment, the friction member 10 contains TiCu, Ti 2 Cu, Ti 3 Cu 4 、Ti 2 Cu 3 and TiCu 4 At least one of them is an intermetallic compound. The friction member 10 may also contain TiC and Cu 3 Ti 3 at least one of O.

One embodiment of a bicycle brake friction member includes an intermetallic compound derived from a first metal and a second metal, and a metallic phase derived from the first metal.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority to prior U.S. Patent Application Serial No. 14 / 521472, filed October 23, 2014 and claims prior U.S. Patent Application Serial No. 14 / 583 / 193, filed December 26, 2014 Priority of , the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to bicycle components, and in particular to friction members for bicycle brakes. Background technique [0004] The physical properties required for bicycle components vary depending on the type of bicycle component. Some bicycle components require satisfactory tensile strength. Some bicycle components require satisfactory wear resistance. Other bicycle components require satisfactory tensile strength and satisfactory abrasion resistance. [0005] When a brake lever is operated, the bicycle brake moves a friction member and generates a braking force from friction of the f...
