    • Abstract
  • FeBC coating with different boron and carbon contents were prepared by wire-arc spraying. The effect of B and C contents on the microstructures and wear resistance of coatings were analyzed by optical microscope,X-ray diffraction(XRD),scanning electron microscopy(SEM),microhardness and abrasive wear testing machine. The results indicate that there are micro-cracks and unmelted particles in the as-deposited Fe-based coatings. With the increases of B and C contents,the unmelted particles increase,the Fe2B,Fe23(C,B)6 hard phase can improve the hardness and wear resistance of the coating significantly. In this studies,the coating with 8% boron and 0. 4% carbon has the best wear resistance,and with the increases of B and C contents,the wear resistance decreases.
