The crankshaft of automobile engines needs to withstand high-frequency torque impact, and the traditional nitriding treatment has a thin hardening layer (≤ 0.8mm), which is prone to wear and fatigue cracks, with a service life of only about 100000 kilometers.
The Daokedao laser cladding equipment adopts the local cladding technology of crankshaft journal, with a cladding layer thickness of 1.5-2mm, a stable hardness of HRC62-65, and a wear resistance four times that of traditional nitriding. The device has a low heat input and a crankshaft deformation of ≤ 0.01mm, ensuring transmission accuracy.
The service life of the strengthened crankshaft has been extended to over 300000 kilometers. After a certain car company adopted this technology, the engine failure repair rate has been reduced by 90%, significantly reducing after-sales costs and meeting the high reliability requirements of the automotive industry.
