| Abstract: | Ni-based composite coating reinforced by TiN particles were prepared on the surface of Q345D steel by means of argon arc cladding technique using Ti,BN and Ni powders as raw materials.The microstructure of the clad layer was observed by scanning electron microscope(SEM) and X-ray diffraction analysis(XRD).The TiN exhibited sphericity,irregular ellipse and dendrite shapes.The performance of coating were investigated by microhardness test and friction wear machine.The average hardness of coating was about 840 HV.The argon arc clad composite coating had high hardness and excellent wear resistance under dry sliding wear test conditions. |
