“…In contrast, the advantage of laser cladding is metallurgical bonding with matrix structure, forming high performance coating with uniform and compact structure, low dilution and small heat-affected zone [6,7]. Researchers have done a lot of work in this field [8][9][10][11][12][13]. Wang et al [8] prepared a layer of Ni-based alloy on the surface of thick plate by plasma spraying, and then cladded the coating with YAG pulse laser, the wear test showed the laser cladding layer performed 14 times higher wear resistance compared to copper substrate.…”

Fe-Co duplex coating has been successfully deposited onto pure copper surface by Nd:YAG laser cladding. The morphology and microstructure were investigated by optical microscopy (OM), scanning electron microscopy (SEM) and x-ray diffraction (XRD). Mechanical properties of the samples have been evaluated by microhardness measurement and wear properties. Experimental results showed that the coating was free of cracks and voids, and good metallurgical bonded to the substrates. The surface of the Fe-Co duplex coating was mainly composed of α-Co solid solution, CoC x , Fe 0.64 Ni 0.36 and a number of carbides. The microhardness of the Co-based coating reached 438.6 HV 0.2 , which was about 5 times of Cu substrate (90.5 HV 0.2 ). The wear test showed the average wear rate of Fe-Co duplex coating was 19.8% of that of copper matrix. The hardness and wear resistance of the Fe-Co duplex coating was significantly improved.

“…Laser surface cladding (LSC) on metal substrates is a nonequilibrium process with high cooling rates (103–108 K/s) that results in the formation of metastable phases by exceeding the solid-solubility limit beyond the equilibrium phase diagram through excellent metallurgical bonding to substrates [ 1 , 2 , 3 , 4 ]. Over the past few years, LSC has been demonstrated to represent a novel coating technology for improving the wear resistance of Cu substrates; thus far, Ni-, Co-, and Mo-based coatings have been reported [ 5 , 6 , 7 ]. Zhang et al laser cladded Ni-based alloy onto pure Cu substrates with an average coating hardness of 360 HV [ 8 ].…”

Microstructure and Antiwear Property of Laser Cladding Ni–Co Duplex Coating on Copper

Ni–Co duplex coatings were cladded onto Cu to improve the antiwear properties of Cu products. Prior to laser cladding, n-Al2O3/Ni layers were introduced as interlayers between laser cladding coatings and Cu substrates to improve the laser absorptivity of these substrates and ensure defect-free laser cladding coatings. The structure and morphology of the coatings were characterized by scanning electron microscopy and optical microscopy, and the phases of the coatings were analyzed by X-ray diffraction. Their hardness was measured using a microhardness tester. Experimental results showed that defect-free composite coatings were obtained and that the coatings were metallurgically bonded to the substrates. The surface of the Ni–Co duplex coatings comprised a Co-based solid solution, Cr7C3, (Fe,Ni)23C6, and other strengthening phases. The microhardness and wear resistance of the duplex coatings were significantly improved compared with the Cu substrates. The average microhardness of the cladded coatings was 845.6 HV, which was approximately 8.2 times greater than that of the Cu substrates (102.6 HV). The volume loss of the Cu substrates was approximately 7.5 times greater than that of the Ni–Co duplex coatings after 60 min of sliding wear testing. The high hardness of and lack of defects in the Ni–Co duplex coatings reduced the plastic deformation and adhesive wear of the Cu substrates, resulting in improved wear properties.
