“…Often, 316L stainless steel is used in marine environments, and it is a common manufacturing material for important ship components [9,10]. Nowadays, severe corrosion has been found on the materials used in the South China Sea region as a consequence of its unique atmosphere (i.e., high temperature, relative humidity, and UV light).…”

The effect of rare earth oxides on the microstructure and corrosion behavior of laser-cladding coating on 316L stainless steel was investigated using hardness measurements, a polarization curve, electrochemical impedance spectroscopy (EIS), a salt spray test, X-ray diffraction, optical microscopy, and scanning electron microscopy (SEM). The results showed that the modification of rare earth oxides on the laser-cladding layer caused minor changes to its composition but refined the grains, leading to an increase in hardness. Electrochemical and salt spray studies indicated that the corrosion resistance of the 316L stainless steel could be improved by laser cladding, especially when rare earth oxides (i.e., CeO2 and La2O3) were added as a modifier.

“…The average surface hardness of NiCr-5%, 10% and 15% Ti 3 SiC 2 coating was 223 6 8.65, 255 6 10.71 and 267 6 6.43 HV 0.5 , respectively, showing that the NiCr-15%Ti 3 SiC 2 coating exhibited the highest hardness. In this case, the precipitates in the NiCr-Ti 3 SiC 2 coating were filled along grain boundary to play the strengthening effect (He et al, 2020), and more Ti 3 SiC 2 particles were introduced in the NiCr-15% Source: Authors' own creation Ti 3 SiC 2 coating, and the hard phases resulted in higher hardness (Li et al, 2019b).…”

Purpose This paper aims to investigate the effect of Ti3SiC2 on the high-temperature tribological behaviors of NiCr coating, which was beneficial to improve the friction-wear performance of hot work mold. Design/methodology/approach NiCr-Ti3SiC2 coatings were prepared on H13 steel substrate by laser cladding. The microstructure, phases and hardness of obtained coatings were analyzed using a super-depth of field microscope, X-ray diffraction and microhardness tester, respectively, and the tribological performance of obtained coatings at 500°C was investigated using a high-temperature tester. Findings The results show the NiCr-Ti3SiC2 coatings are comprised of γ-Ni solid, solution, TixNiy, TiC and Ti3SiC2 phases, and the coating hardness is increased with the increase of Ti3SiC2 mass fraction, which is contributed to the fine-grain and dispersion strengthening effect by the addition of Ti3SiC2. The NiCr-Ti3SiC2 coatings present excellent friction reduction and wear resistance by the synergetic action of Ti3SiC2 lubricant and hard phase, and the wear mechanism is predominated by abrasive wear and oxidation wear. Originality/value Ti3SiC2 phase was used to reinforce the tribological performance of H13 steel at high temperature, and the roles of friction reduction and wear resistance were discussed.

“…In previous studies, Cr 3 C 2 -NiCr coating fabricated by HVOF showed strong corrosive wear resistance [25][26][27] and laser cladding Ni625 coating exhibited excellent corrosive wear resistance [28]. In this study, the author intended to combine the advantages of both layers to improve service life under the combination of fatigue and corrosion conditions.…”

In order to improve material service life under a fatigue and corrosion coupling environment, a high-velocity oxygen fuel (HVOF) Cr3C2-NiCr coating with a bonding layer was prepared. The objective was to obtain the optimum bonding layer for the HVOF Cr3C2-NiCr coating, which included a laser cladding (LC) Ni625 layer, extreme high-speed laser material deposition (EHLA) Ni625 layer and HVOF NiCr layer. Fatigue properties of the samples with various bonding layers were investigated by means of a four-point bending fatigue test. Electrochemical impedance spectroscopy (EIS) and the salt spray test were executed after the bending fatigue test to simulate the interactive effect of fatigue and corrosion atmosphere. Failure surfaces were characterized by scanning electron microscopy (SEM) and an energy-dispersive spectrometer (EDS) to indicate the details of corrosion products. Corrosive behaviors of samples were adequately demonstrated according to the results, which included the curves of potentiostatic polarization, impedance magnitude and phase degree, and corrosion products. The result showed that the cycles of perforative cracking for the sample with the EHLA Ni625 bonding layer was almost three times than that of the sample with the HVOF NiCr layer. The magnitude of EIS reduced from ~105 to ~103 for the sample after BFT. Eventually, the main improvement mechanism of the HVOF Cr3C2-NiCr coating with the EHLA Ni625 bonding layer was attributed to the grain refinement of the bonding layer and performed a good level of metallurgical bonding with the substrate.
