In the present study, an attempt has been made for deposition of B4C-NiCr powder on low carbon steel by laser cladding to improve wear resistant of the substrate. clad powder blends of B4C and NiCr of composition 10%B4C+90%NiCr (80%Ni20%Cr) were deposited by laser cladding using a continuous wave CO2 laser under optimum processing conditions. The result showed that the microstructure of the clad layer consisted of dispersion of B4C particles in the form of nickel borides (NiB, Ni2B). The wear resistance of laser clad low carbon steel was significantly improved as compared to as-received low carbon steel substrate. The wear rate of laser clad low carbon steel (0.1563×10-9 kg/Nm) is much lower than that of as-received substrate (0.1892×10-9 kg/Nm).
