چکیده انگلیسی
A boriding treatment was applied to AISI 1020 steel at 1000 °C for 4 h. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and the Knoop microhardness test. The loads and abrasive slurry concentrations used in the micro-abrasion tests (fixed-ball) were 0.49-0.98 N and 0.5-1.0 g/cm³, respectively. Silicon carbide (SiC) abrasive powders (5 µm) were used in the abrasion experiments. The wear coefficient and mechanisms were compared with those obtained from untreated samples. The XRD analysis revealed the presence of the Fe2B phase on the borided samples. The iron borided layer was 177 µm thick and had a hardness of 2100 HK0.01. The wear mechanism for the borided samples was rolling abrasion while grooving abrasion with micro-rolling occurred in the untreated samples.
