Microstructure and surface quality of SLM printed miniature helical gear in LSPwC
Original language description
The present work describes the influence of underwater laser shock peening without coating on selective laser melting manufactured meso-size helical gears.Five experiments were conducted using energies in the 200mJ up to 1J,while the spot size and overlap were kept constant as 1mm and 90%,respectively.Responses were measured and compared in terms of surface residual stresses,surface roughness,and microstructure of LSPwC-treated samples.Results show the development of significant compressive residual stresses in the root of the LSPwC processed helical gear,where it changes the state from tensile +45MPa to compressive −421MPa.Surface roughness has shown improvement,while volumetric material peak confirms the reduction by over 50%.Microstructure study was performed at the surface and by cross-section using scanning electron microscopy and electron backscatter diffraction analysis.The grain refinement and change in misorientation were observed,confirming plastic deformation.
