【 摘 要 】

Boriding treatment was carried out at 850, 900, 950, 1000 and 1050 °C for 2, 4 and 8 h on carbon steel. The effect of some treatment parameters such as the chemical composition of the mixture, boriding temperature and time were investigated. X-ray diffraction (XRD), scanning electron microscopy (SEM) and microhardness tests were used to describe the formed boride layers. Some properties of boride layers have been studied such as corrosion and wear resistance. The obtained results confirm that the corrosion resistance of boride carbon steel was improved compared to no-boriding steel. The dry abrasive wear resistance of boride alloy samples is about 5 times greater than that of non-boride ones.
