| Summary: | This research examines the reciprocating wear behavior of AM60 magnesium alloys with and without polylactic acid (PLA) coating layers. For this objective, fused deposition modeling (FDM) 3D printing is employed to produce the PLA parts. Reciprocating wear tests are carried out under two different forces of 5 N and 10 N to determine the friction coefficients and the wear rates. Consequently, under applied forces of 5 N and 10 N, the PLA coating reduced the friction coefficient by 59.82 % and 42.16 % respectively, and the wear rate by 51.44 % and 75.76 %, respectively. Uncoated samples presented high wear rates with increasing applied forces, whereas the coated samples manifested better wear resistance, indicating the protective function of PLA. Additionally, in comparison with changing the force, PLA coating demonstrates greater effectiveness at enhancing wear properties. As regards the wear mechanism, energy-dispersive spectroscopy (EDS) and field-emission scanning electron microscopy (FESEM) results indicated the delamination and adhesion of non-coated samples and corroborated that the PLA coating has a positive effect on enhancing the wear resistance of the AM60 magnesium alloys. |
