“…The formation of oxides may be based on the air mixed into the powders. However, there is no diffraction peak of WC in the XRD pattern, which may be due to the low content of WC, and some of it is decomposed and burned during laser cladding [ 34 ].…”

Laser cladding technology is used to fabricate CoCrFeNi HEA/WC composite coatings with different mass fractions of WC on the surface of 316L stainless steel. The microstructures of HEA/WC composite coatings were analyzed by combining multiple characterization techniques. The results show that the HEA/WC composite coatings have good surface formation without pores and hot cracks, and the metallurgical bonding is well formed between the coating and the 316L SS substrate. Under the action of a laser beam and molten pool, WC particles partially or slightly melt and diffuse to the matrix, which hinders the orderly growth of grains and forms multiple strengthening. The phase structure of the HEA/WC composite coatings is composed of a main phase with FCC. The hardness and corrosion resistance of the HEA/WC composite coatings are clearly enhanced, and the HEA/WC composite coating with 5% WC has optimum properties.

“…Consequently, WC particles may easily spall during the friction process, leading to abrasive wear and grooves on the friction surface. As can be observed from Figure 6 , when the magnetic field intensity increases, there are no obvious furrows and large spalling layers, but only some small spalling pits, indicating the decreasing adhesive and abrasive wear [ 27 , 28 ]. This is because with the growing intensity of the alternating magnetic field, the WC particles are uniformly distributed.…”

Ni60A/WC composite coating is prepared on 45 steel substrate by alternating-magnetic-field-assisted laser cladding. We compare the effects of different magnetic field intensity on WC particle distribution, microstructure, phase composition, microhardness and wear; in addition, the mechanism of alternating magnetic fields on cladding layers is briefly analyzed. The results show that an alternating magnetic field can significantly homogenize the distribution of WC particles. WC particles at the bottom are stirred and dispersed to the middle and upper area of the laser pool. The distribution of WC in the bottom region 6 of the coating decreases from 19.1% to 10%, the distribution of WC in the bottom region 5 decreases from 46.46% to 33.3%, the WC distribution in the top region 1 of the coating increases from 0 to 7.7% and the WC distribution in the top region 2 of the coating increases from 8.08% to 12.2%. The stirring of alternating magnetic fields strengthens the solute convection in the laser pool, refines the snowflake-shaped carbide hard phase and improves the coating microhardness and wear property, and adhesive wear and abrasive wear decrease gradually with increasing magnetic field strength.

“…The metal matrix composite showed great potential in overcoming this problem. [86][87][88][89] The metal matrix composites of the Inconel-718 have also been prepared using various techniques of additive manufacturing such as SLM, PBF methods, etc. 90,91 Thus understanding the tribological properties of these composites becomes necessary for their application in respective fields.…”

Superalloys are a group of engineering alloys designed to operate at elevated temperatures, and they find application in various engineering sectors where a high-temperature application is required such as nuclear power plants, steam turbines, and aircraft. There are three important classes of superalloys, that is, iron-based, cobalt-based, and nickel-based superalloys. Among them, nickel-based superalloys find great application at both low and high temperatures due to their higher mechanical strength, good fatigue life, excellent wear, and corrosive resistance. This review article aims to review the tribological studies of the nickel-based Inconel superalloys. The article deals with the systematic studies of wear behavior, wear mechanism, and nanostructured glaze layer formation over the wear surfaces. The effect of load and temperatures influencing the wear rate and wear mechanisms of nickel-based superalloys are also discussed in detail. Along with that, the focus of this review article is to discuss the advancement in the tribological studies of the Inconel-718 superalloy. The development in the Inconel-718 alloys (surface alloying, laser shot peening, composites, microstructure engineering, etc.) to improve wear resistance is also discussed in a systematic manner. This article is expected to assist the researchers in identifying the trend and research gaps so that they can contribute to further tribological developments of nickel-based superalloys.
