Laser cladding hot crack repair of brake disc, restoring braking safety performance of Daokedao equipment
Date:2025-10-27 15:54     Source:daokedao     Browse:52

Long term exposure to high temperature and sudden cooling during braking can easily cause fine and micro thermal cracks in brake discs. If not treated in a timely manner, the cracks will gradually expand, leading to the risk of brake disc fracture. Traditional polishing repair cannot cure deep damage, and laser cladding crack repair of brake discs has become a key technology to ensure braking safety.

The Daokedao laser cladding equipment adopts micro beam laser crack repair technology. After accurately locating the crack position, specialized repair alloy powder is melted and injected into the crack to form a laser cladding repair layer that is tightly bonded to the substrate. The entire repair process is temperature controlled to avoid secondary thermal damage, and the strength of the repaired crack area is consistent with the original material, completely eliminating safety hazards. As a professional laser cladding equipment for braking systems, it can also perform overall laser cladding strengthening on the surface of brake discs, cladding wear-resistant and heat-resistant coatings to enhance their thermal fatigue resistance and reduce the occurrence of thermal cracks from the root.

The brake discs processed by the Jingdao Kedao laser cladding equipment have a service life extended by more than 2 times, significantly improved thermal stability during braking, and reduced braking distance by 5% -8%. Whether it is passenger cars, commercial vehicles, or heavy-duty construction machinery brake discs, efficient repair and safety upgrades can be achieved.
