Abstract

A Fe₃O₄/Diamond-like carbon (DLC) coated carburized layer on M50NiL steel surface was fabricated by one-step plasma-assisted method in gaseous acetone at 550 °C. The surface layer showed high hardness (13.94 ± 0.92 GPa) and elastic modulus (314.18 ± 9.25 GPa) due to synergistic effect of rigid DLC and mild Fe₃O₄. The carburized layer with gradual hardness distribution served as supporting layer. The Fe₃O₄/DLC-containing carburized layer showed lower friction coefficient (about 0.25) and 97.6% reduction in wear rate (1.53 × 10^− 6 mm³ N^− 1 m^− 1) compared with untreated specimen due to the lubricating effect and gradient multilayer structure. The tribological properties demonstrated that the treatment in present work has great advantages over other surface treatment. Moreover, the formation mechanism of the functionally graded carburized layer was discussed. The results pointed out a simple way to greatly improve wear resistance for steels.
