Abstract
Laser cladding is a kind of surface strengthening process to improve the mechanical properties of transmission part. The effects of process parameters and materials on geometric accuracy and microstructure are studied to increase the cladding layer quality. The cladding layer geometry is also affected by the surface morphology and cladding position of substrate. In this paper, laser cladding process with T15 powder is applied at the different radial positions of 42CrMo cylindrical samples with different diameters. The influence of surface curvature and cladding position on the cladding layer shape is studied. The single layer asymmetry is directly influenced by the angle between vertical direction and radical direction of cladding position. With the increase of the angle from 0° to 50°, the asymmetry increases from 0% (symmetry), up to 14.3%. The cladding layer microstructures consisted of dendrite, columnar crystal, and equiaxed crystal.
