Brake disc and anti-corrosion treatment method of brake disc

The invention provides a brake disc and an anti-corrosion treatment method of the brake disc. The surface of the brake disc comprises a friction area, wherein a removable coating layer is arranged in the friction area. According to the brake disc and the anti-corrosion treatment method of the brake disc, the removable coating layer is arranged in the friction area in the surface of the brake disc, so that the brake disc is prevented from being corroded by the external environment during transportation and storage; when the brake disc is used, the surface of the friction area of the brake disc is smooth after the removable coating layer is removed, and abrasive wear caused by falling of a zinc spraying layer of the friction area cannot occur during operation of the brake disc. Compared with the prior art, the anti-corrosion problem of the friction area of the brake disc during transportation and storage can be solved, the problems of vibration, abnormal sound and the like of the brake disc during yawing can be
