| Abstract | Laser cladding process causes thermal stresses, which lead to the appearance of residual stresses and substrate distortions. In this study, laser cladding was applied to a 5052 aluminium alloy using a cw Nd:YAG laser and coaxial injection of Al 50Si powders. Residual stresses were quantified by X-ray diffraction and by sample strain measurements. The differences in the results obtained by these two methods highlighted the influence of the heat-affected zone. A model of three strain domains has explained these differences: the coating, the HAZ and the substrate. Experiments identified an optimal treatment speed, leading to maximum compression stresses. Moreover, at a certain fixed speed, thermal stresses balanced each other in the sample leaving the substrate undistorted. |
