CORROSION AND WEAR-RESISTANT BRAKE DISC AND RELATED METHODS
This abstract first appeared for US patent application 20250102028 titled 'CORROSION AND WEAR-RESISTANT BRAKE DISC AND RELATED METHODS
Original Abstract Submitted
a corrosion and wear-resistant brake disc is disclosed. the brake disc comprises a brake body having at least one braking surface, and a corrosion and wear-resistant coating electrodeposited on the braking surface. the corrosion and wear-resistant coating comprises a precipitation-hardened cobalt-phosphorus (cop) alloy and exhibits a vickers hardness of from about 900 to about 1050 hv. a method of preparing the brake disc is also disclosed, and comprises electrodepositing a cobalt-phosphorus (cop) alloy onto at least one braking surface of a disc body to a thickness of at least about 150 �m to give a coated disc body. the method also comprises heat treating the coated disc body to precipitation harden the cop alloy and give the corrosion and wear-resistant coating on the braking surface.
