TiAlCoCr x FeNihigh-entropy alloys (HEAs) coatings were fabricated on the surface of Ti6Al4V by laser cladding. Their microstructural evolution with the increase in x value (x=0, x=1.0, x=2.0) was investigated in detail. Besides that, the investigation into the effects of the Cr content on their corrosion behaviors and mechanical properties (in terms of hardness and wear resistance) was also carried out comprehensively. The results indicated that two kinds of phases (a solid solution with thehexagonal close-packed (HCP) structureand Ti 2 Ni) were synthesized in the coatings, and the HCP content was gradually increased with the increase in x accompanied with the decrease in Ti 2 Ni content. A HEA coating only composed of single HCP was successfully prepared when x reached 2.0. The electrochemical and immersion tests all confirmed that the coating with x=2.0demonstrated the most excellent corrosion resistance in a0.1 mol·L −1 HCl solution from different aspects including corrosion tendency and corrosion rate without the applied potential, the formation difficult/stability of the passive film and the dissolution rate in the passive state, and corrosion surface morphology. The averagemicrohardness values of the coatings weregraduallyincreasedfrom 656HV 0.2 to 800 HV 0.2 with increasing xfrom 0 to 2.0, which wereabout double that of the substrate (350 HV 0.2 ). Wear resistance of the coatings also exhibited the upward tendency with increasing the x values (0.562 mm 3 at x=2.0, 0.640 mm 3 at x=1.0, 0.641 mm 3 at x=0 and 1.419 mm 3 for the substrate). More Cr addition into the cladding material will contribute to the formation of a HEA coating composed of single HCPwith excellent corrosion and wear resistance.

“…The severe tribo-oxidation of bare M50 steel indicates that atmospheric oxygen resolved into JP-10 and then oxidized the active surfaces exposed after asperity-to-asperity contact. It is well known that a Ta coating/film will be oxidized to form self-lubricious Ta 2 O 5 with a low COF during ambient friction [58,[61][62][63]. The M50 steel wear topography (2.0 GPa, Figure 6) clearly shows the formation of thick and dark oxidation layers on the wear track, but similar oxidation layers were not observed on the worn Ta alloying coating (2.0 GPa, Figure 8; 3.5 and 4.0 GPa, Figure 9).…”

“…These comparisons in wear topography and chemical composition demonstrate that the tribo-oxidation of Ta alloying coating was quite weak. Yet, very thin protective Ta 2 O 5 films could be formed on the worn surfaces, which effectively inhibited the invasion of oxygen toward the inner layer and M50 steel substrate [63][64][65][66]. Therefore, the excellent boundary tribological performance of HCPEB-treated Ta coating cannot be primarily attributed to the self-lubricious properties of the lubricious oxide films (e.g., Ta 2 O 5 ) that were formed on the wear track during the friction test.…”

High-current pulsed electron beam (HCPEB) irradiation commonly induces crater-like cavities on irradiated surfaces, making them tribologically resemble textured ones. However, the effect of crater-like cavities on the lubricated tribological properties of HCPEB-treated surfaces has not been reported in the literature. This work was aimed at exploring the potential texturing effect of the crater-like cavities. Surfaces with continuous and uniform crater-like cavities were prepared through HCPEB irradiating a 400-nm thick Ta coating that was pre-deposited on polished M50 steel. Their boundary tribological behaviors were studied while sliding in chemically inert, low-viscosity hydrocarbon fuel JP-10 against a Si3N4 ball under 2.0–4.0 GPa. At 2.0 GPa, the coefficient of friction (COF) and wear rate of the polished M50 steel were above 0.16 on average, with large fluctuation, and 1.49 × 10−5 mm3/N·m (a rectangle-like profile of 167.9 μm × 8.1 μm), respectively. In comparison, the HCPEB-treated Ta coating had a stable, marginally fluctuant COF of 0.11 and a near-zero wear rate. Under other higher loads, the HCPEB-treated Ta coating still exhibited a stable COF of 0.11 on average with small fluctuation, and its wear track width was only half that of the M50 steel. The analysis of the wear topographies indicates that the substantial reduction in both the COF and wear rate was mainly due to the texturing effect originating from the crater-like cavities.

“…The protecting layer exhibits excellent corrosion and wear resistance for complex working environments [6][7][8]. Compared with traditional surface modification techniques, such as thermal spraying, physical vapor deposition, and chemical vapor deposition, coatings deposited by laser cladding possess many superior characteristics, such as a lower dilution rate, higher density, and a lower number of pores [9,10]. The chemical composition and microstructure of the layers can be changed due to the characteristics of laser processing [11].…”

In order to better understand how a high energy input and a fast cooling rate affect the geometric morphology and microstructure of laser cladding aluminum composite coatings, a three-dimensional (3D) transient finite element model (FEM) has been established to study the temperature field evolution during laser cladding of AlSiTiNi coatings on a 304 stainless steel substrate. In this model, a planar Gauss heat source and a temperature selection judgment mechanism are used to simulate the melting and solidification process as well as the geometric morphology of the laser cladding coatings. The differences in physical characteristics of the cladding materials before and after melting are considered. The results of thermal simulations, including temperature history, temperature gradient, and solidification rate, of the laser cladding coatings are investigated. Corresponding experiments, conducted using an IPG-YLS-5000 fiber laser, are used to verify the simulation results. The experimental observations agree well with the theoretical predictions, which indicates that the established model is valid.
