Abstract

The invention discloses a high strength corrosion-resistant coating material for a brake disc. The raw materials of the high strength corrosion-resistant coating material for the brake disc are prepared from Al, Mg, B, Zr, Sr, Mn, Ti, Si, Ni, Cu, Ce, La, Y and Er, and the balance of Zn and inevitable impurities. The high strength corrosion-resistant coating material for the brake disc disclosed bythe invention can be firmly combined with a brake disc base body, is good in compactness and improves the performances, for example, surface strength, corrosion resistance and the like, of the brakedisc, so that the service life of the brake disc is prolonged, and the reliability of the brake disc is improved.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to a high-strength corrosion-resistant coating material for brake discs. Background technique [0002] As an important part of the automobile braking system, the brake disc is related to the driving safety of the car. The corrosion resistance of the brake disc will directly affect the service life and reliability of the brake disc. The existing brake disc has low surface strength and poor corrosion resistance, which affects the service life and reliability of the brake disc. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a high-strength corrosion-resistant coating material for brake discs, which can be firmly combined with the brake disc substrate, has good compactness, and effectively improves the surface strength and corrosion resistance of the brake disc. The service life of the...
