Study on the Microstructure, Mechanical Properties and Wear Performance of Nickel-Chromium-Based Alloy Coatings by DU Dianxi, RUI Shuju, YANG Xingbin

“…In order to enhance the mechanical and wear properties of the surface of 12Cr1MoV steel,a mixture of nickel-chromium alloy powder and nickel-coated tungsten carbide (WC) powder were utilized as raw materials.Laser cladding technology was employed to fabricate a nickelcoated WC nickel-chromium-based alloy coating on the surface of 12Cr1MoV steel.The microstructure, phase composition, mechanical properties and wear performance of the coating were analyzed using scanning electron microscopy, X-ray diffraction (XRD), microhardness testing, impact testing and wear testing machines for particle wear, erosive wear and frictional wear.The effects of varying amounts of nickelcoated WC on the microstructure, phase composition, microhardness, impact performance and resistance to erosive wear, abrasive wear and frictional wear of the coating were investigated.Results showed that the nickel-coated WC coating was characterized by a dense microstructure,with phases including (Ni,Cr) solid solution,Cr23C6,Fe3W3C,Fe6W6C and WC.As the content of nickel-coated WC was increased,the microstructure of the coating was refined,and simultaneous improvements in mechanical and wear properties were achieved.When the nickel-coated WC content reached 30%(mass fraction), the coating structure was dense and significantly refined, and the coating showed high hardness, toughness and wear resistance.The microhardness of the 30%nickel-coated WC coating was 760 HV, with an impact absorbed energy of 54.1 J, along with a low friction coefficient and excellent resistance to frictional wear.The mass loss due to erosive wear and abrasive wear was determined to be 1/28 and 1/48 of the substrate’s mass, respectively.The mechanical and wear properties of the 30%nickel-coated WC coating were found to surpass those of other coatings and the substrate.…”

Effects of Laser Remelting on Microstructure and Wear Properties of Ni-Based Coating Prepared by Electrospark Deposition by GAO Yu-xin, WANG Jun-bo

“…Ni-based coating by electrospark deposition was remelted by pulse laser equipment in order to remove cracks, holes and inclusion in the coating.The changes in microstructure and mechanical properties of the coating were investigated by SEM, XRD and frictional testing machine.Results showed that the dendritic structure of the coating was changed into evenly distributed superfine grains after laser remelting, and the grains in the upper of the coating reached nanometer size.Meanwhile, the precipitation of hard phases, such as CrB, Cr7C3 and FeNi3, were observed.Laser remelting reduced the cracks, pores and inclusions in the coating.The effect of grain refinement improved the hardness and wear resistance of the coating.The wear mechanism of Ni-based coating was changed from fatigue wear to abrasive wear after laser remelting treatment.…”
