“…After the wear test, the profiles, morphologies and chemical elements of wear tracks were analyzed using three-dimensional non-contact surface mapping profile surface (Dektak XT, Bruker, Billerica, MA, USA), SEM and EDS. The wear rate ( W ) were calculated using following equation [ 11 , 17 ]:

where “ R ” is the radius of the wear track, “ A ” is the cross-section area of the wear track, “ F ” is the normal load, and “ S ” is the total sliding distance.…”

SK5 steel is the base material used for the preparation of the wrinkle scraper, whose service life strongly affects the working efficiency and economic benefits. In this work, WC–Cr3C2–Ni coating was deposited on the SK5 steel substrate by using High-velocity air fuel spray (HVAF) and Laser cladding (LC) processes respectively, named HVAF-WC coating and LC-WC coating. The microstructure and wear resistance of both coatings were analyzed, and were compared with the substrate sample. Results showed that the coatings were adhesive well onto the substrate. More WC with fine crystals is retained in HVAF-WC coating due to low flame flow temperature, while WC of LC-WC coating is characterized by columnar crystals. The wear rate of HVAF-WC and LC-WC coating was 4.00 × 10−7 mm3/(N•m) and 3.47 × 10−6 mm3/(N•m), respectively, which was two and one orders of magnitude lower than SK5 steel with 3.54 × 10−5 mm3/Nm. HVAF-WC coating exhibited the best wear resistance because of significant fine grain strengthening, which wear mechanism is mainly dominated by abrasive wear. Thus, it was thought that HVAF-WC coating is more effective ways to improve the wear resistance of SK5 steel, comparing with LC-WC coating.

“…Compared to traditional High-velocity oxygen fuel spray (HVOF), HVAF produces lower flame temperatures and higher particle velocities [ 7 , 8 , 9 ]. Differently, laser cladding (LC) produces coating rapidly under high energy density laser beam and solidifying on the protected substrate with a metallurgical bonding [ 10 , 11 ].…”

Surface modification of nickel‐based 625 alloy is performed using a vacuum electron beam to improve its surface properties. The development of the microstructure is analyzed through scanning electron microscopy, X‐ray diffraction, and transmission electron microscopy. The tribometer RETC (MFT‐5000) is used to assess the wear resistance of the modified surface. The results demonstrate that the microstructure of the cladding zone exhibits columnar growth of the face‐centered cubic phase. As the scanning speed increases, the Cube texture s gradually weak, surface hardness increases, and both wear volume and wear rate decrease, thereby improving wear resistance. The maximum surface hardness is achieved at a scanning speed of 400 mm min−1, with a value of 489.8 HV, 1.977 times higher than the substrate. The minimum wear volume measures 0.1518 mm3, and the wear rate is likewise at its lowest point, measuring 0.506 × 10−5 mm3 N−1 m. Compared to the substrate, the material demonstrates an 88.44% reduction in wear rate and an 8.65‐fold improvement in wear resistance. These results demonstrate the significant enhancement of surface properties in Inconel 625, through surface modification using a vacuum electron beam.

“…[9][10][11] Guo et al 12 found that the WC greatly increased the wear resistance of Ni-based coating, which was attributed to the high hardness of WC phase. Yan et al 13 also prepared the NiCrBSi-WC on PH13-8Mo steel, and found that the hardness was more than twice that of substrate, and the obtained coating had excellent tribological performance and low wear rate. Previous studies have also indicated that the Ni-WC coating has high wear resistance, which may apply to the surface modification of plastic molds.…”

Ni–WC coatings with the different Ti2SnC mass fractions were prepared on the substrate of S136 steel by laser cladding (LC), in which the metallurgical bonding was formed at the coating interfaces. The microstructure and phases of obtained coatings were analyzed using a super depth of field microscope (SDFM) and X-ray diffraction (XRD), respectively. The effect of Ti2SnC mass fraction on the microstructure and tribological properties of Ni–WC coating were investigated using a ball-on-disc wear tester, and the wear model was also established to analyze the role of Ti2SnC phase in the friction process. The results show that the Ni–WC–8%Ti2SnC coating has the lowest coefficient of friction (COF) and wear rate among the three kinds of coating, and the wear mechanism is abrasive wear, which is contributed to the friction reduction and wear resistance roles of Ti2SnC phase. Furthermore, the COF and wear rate of Ni–WC coating can be reduced by the addition of appropriate Ti2SnC mass fraction, which may provide the reference for the friction and wear of Ti2SnC MAX phase in the coating field.
