Different parts of a shaft often bear different types of loads (such as the journal requiring wear resistance, the shaft body requiring torsion resistance, and the transition zone requiring fatigue resistance). Traditional single material or integral heat treatment is difficult to achieve optimal performance configuration. The flexible manufacturing characteristics of laser cladding make it possible to design gradient functional materials with "one location, one strategy".
This exploration focuses on the transmission shaft of a heavy machinery, which is designed and coated with alloys of different compositions in different functional areas: 1) At the shaft neck where the bearings are matched, a high carbon and high chromium iron-based alloy is melted to obtain a high hardness of HRC 60 or above to ensure wear resistance; 2) At the key slot where torque is transmitted, medium carbon alloy steel with better toughness is melted to withstand impact loads; 3) In the stress concentrated rounded transition zone, alloy that matches the properties of the substrate is melted and compressive stress is introduced through laser shock strengthening.
This gradient design that combines rigidity and flexibility maximizes the overall performance of the shaft, solving the problem of neglecting one aspect over another on traditional shafts, and representing the advanced stage of laser remanufacturing from "restoration" to "optimization".
