In this study, we investigated the wear behavior of borided ISO C45 carbon steel and SAE-48, SAE-783 soft bearing alloys. Boriding was carried out in powder-pack processes at temperature of 950 ℃ for 8 h. High-lead alloy SAE-48 and aluminum alloy SAE-783 was used on low carbon steel. Sliding pairs under the examination were lubricated with 15 W/40 Lotos mineral engine oil. The wear behaviors of borided steel and SAE-48, SAE-783 alloys were characterized by using block-on-ring tester. The testing loads were 0.5 kN, 1.0 kN, 1.5 kN, 2.0 kN, respectively. The linear speed between the couples was 0.2 m/s. The linear speed between the couples was 0.2 m/s. The distance of friction was 100 m. Examinations performed with X-ray diffractometer revealed Fe2B, FeB phases in the borided layer. Scanning electron microscope equipped with energy-dispersive X-ray spectrometer on the cross section of the borided layer revealed columnar crystals of Fe2B phase. The soft bearing alloy SAE-48 showed from 3.3 to 4.5 greater linear wear than SAE-783 alloy. The examined pairs showed abrasive and adhesive wear. The abrasive wear was dominant in the pair with SAE-783 bearing alloy. The adhesive wear was dominant in the pair with the SAE-48 bearing alloy. At the loads of 1.0 kN, 1.5 kN, and 2.0 kN the temperature of the SAE-48 bearing alloy was about 20 ℃ greater than the temperature of the SAE-783 bearing alloy. After the tribological tests the SAE-48 alloy showed greater roughness as compared with the SAE-783 alloy. When combining borided steel with a soft bearing alloy it is recommended to use aluminum-based alloy.
