“…By measuring the wear weight The wear weight loss of coatings 1# and 2# is high, and the exfoliated hard ceramic phase with the abraded debris is compacted under the extrusion of the grinding ring. It has been speculated that these compacted layers have some protective effect on the coating, thus improving the wear resistance of the coating [27][28][29][30]. To analyze the effect of these compacted layers on the wear resistance of the coating, the friction wear test was adjusted.…”

In situ NbC-reinforced laser cladding Ni45 coatings have the advantages of high bond strengths, low dilution rates, small heat-affected zones and good wear resistance and have broad application prospects in the field of surface strengthening and repair of workpieces such as automotive molds and engine turbines. Previous studies have mostly used pure niobium powder for in situ synthesis to prepare Ni-based NbC coatings with a high production cost. In this paper, NbC was successfully synthesized in situ in Ni45 powder using inexpensive FeNb65 and Cr3C2. The prepared coating has a uniform microstructure and excellent wear resistance, and the reinforced phases are mainly NbC and Cr23C6. Coating 4# with 25 wt.% FeNb65 + Cr3C2 has the highest microhardness of 776.3HV0.2, about 1.45 times that of the Ni45 coating, and its wear resistance is 36.36 min/mg, about 60.6 times that of the Cr12MoV steel base material and about 23.76 times that of the Ni45 coating.

Laser cladding technology is widely used in component repair and surface strengthening because of its advantages of various powder options and high processing efficiency. This paper outlines the application and research of transition layers in laser cladding and details the advantages of transition layers in terms of bonding performance, defect rate, and cladding thickness. Compared with conventional laser cladding, the composite process with the addition of transition layer has been further improved in terms of organization, mechanical properties, and corrosion resistance. In addition, the repair process of laser cladding to meet the cladding thickness of the parts and avoid the degradation of surface properties is also discussed.
