Microstructure and surface quality of SLM printed miniature helical gear in LSPwC

Popis výsledku v původním jazyce

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.
