“…Among them, laser cladding has a low dilution rate, forms a small heat-affected zone after processing, and has far less effect on the substrate itself than other surface modification techniques and is therefore more favored by scholars. [9,10] Ceramic-metal composite coatings have more than twice the hardness and abrasion resistance of the base material, [11] so they have attracted much attention in the field of surface modification research. Most of these coatings have been studied using TiC, WC, VC, Al 2 O 3 and the addition of other hard phases to enhance iron, cobalt, and Ni based.…”

“…[25] However, with the depth of research, scholars have found that although the addition of ceramic powder in the metal base can effectively enhance the coating microhardness, it does not mean that the more ceramic powder is added, the better. [26,27] Therefore, this study proposes to use TiN, graphite powder, and Ni60 powder mixing, in situ preparation of TiCN-reinforced nickel-based coatings to explore a reasonable powder proportioning scheme. The results of the study can provide reference and theoretical support for the preparation of in situ carbonitride-enhanced coatings by laser cladding.…”

The influence of the ratio of TiN powder, graphite powder, and Ni60 powder on the phase composition, microstructure, microhardness, and wear properties of the TiCN Ni‐based coating on H13 steel was investigated. The findings indicate that varying proportions of TiN powder, C powder, and Ni60 powder have a minimal impact on the coating’s phase composition. The diffraction peak intensity of TiC0.3N0.7 increases with the addition of (C+TiN) in the blended powder, while the crystallinity of TiC0.3N0.7 in the Ni‐based coating with a 30% (C+TiN) mass fraction decreases. The grain structure of the 20% Ni‐based coating is fine and uniform, while the microstructure of the 30% Ni‐based coating is characterized by a large polymerization phase containing Ti elements, with the TiCN‐reinforced phase exhibiting irregular grain morphology. The microhardness HV0.5 of the coating with a 20% (C+TiN) mass fraction ranges from 725 to 772, with an average hardness of 747.8 HV0.5, which is 3.4 times the hardness of the substrate material and 1.3 times the hardness of the Ni‐based coating. As the mass fraction of (C+TiN) in the hybrid powder increases, the friction loss mass of the coating tends to decrease and then increase. The average wear of the Ni‐based coating with a 20% (C+TiN) mass fraction is approximately 22.4% of that of the substrate and 50% of that of the Ni‐based coating, demonstrating excellent wear resistance. The wear mechanism is primarily characterized by brittle spalling and abrasive wear.This article is protected by copyright. All rights reserved.

“…In comparison with the conventional surface modification process, laser cladding exhibits the benefit of higher energy density and lower dilution rate, which enables effective refinement of the tissue and improvement of coating elemental segregation [7][8][9]. Nickel-based powder has favorable corrosion resistance and wettability, and the Cr elements in the melt pool will react with C and B elements to produce Cr 7 C 3 , Cr 23 C 6 , CrB and other phases during the preparation of the coating by laser cladding, which are capable of raising the microhardness and wear resistance of the coating [10,11]. However, as the temperature increases, the phase within the NiCrBSi coating starts to change.…”

Nickel-based coatings obtained by laser melting are broadly applied for surface modification owing to their high bond strength and exceptional wear resistance. Nickel-based laser cladding coatings are also extensively employed in high temperature wear environments. In this paper, the research progress on improving the high temperature wear resistance of laser cladding nickel-based composite coatings was reviewed by introducing a hard ceramic phase, adding solid lubricants and rare earth elements. On this basis, the material system to enhance the high temperature wear resistance of coating was summarized from the perspectives of the type, addition amount, morphology and distribution law of the hard ceramic phase, etc. The synergistic effect of various lubricants on improving the high temperature wear resistance of coating was discussed, and the action mechanism of solid lubricants in the high temperature extreme environment was analyzed. Finally, this paper summarizes the main difficulties involved in increasing the high temperature wear resistance of nickel-based coatings and some problems worthy of attention in the future development.
