“…It has been reported that annealing at more than 400 °C can fully crystallize as-deposited 60NiTi film, which is still amorphous after annealing at 300 °C [29]. Figures 1(a-c) show the SEM images of the crosssectional topographies of the 60NiTi films in different heat-treated conditions.…”

“…Neupane et al [28] found that 60NiTi bulk alloy exhibited excellent tribological performance under dry reciprocating movement, and its high H/E was an important contributor. However, in terms of 60NiTi film, only few studies exist, and they mainly focus on the effects of annealing on hardness and corrosion resistance of sputter-deposited 60NiTi film [29]. In another word, the tribological performance of 60NiTi film remains unexplored.…”

The microstructure, mechanical and micro/nano-tribological properties of the 60NiTi film annealed at different temperature were investigated. The results reveal that annealing as-deposited 60NiTi film at 300, 375, and 600 °C for 1 h leads to structural relaxation, partial crystallization and full crystallization, respectively. Compared with the structurally relaxed structure, the partially crystallized structure exhibits increased hardness but decreased elastic modulus. This is because that the elastic modulus is reduced by Voigt model while the hardness is improved by composite effect. Due to the highest hardness and ratio of hardness to elastic modulus (H/E), the partially crystallized 60NiTi film has the lowest penetration depth and residual depth (i.e., groove depth). Besides, the results also reveal that ductile plowing is the dominant wear mechanism for all the annealed 60NiTi films. Under the condition of the ductile plowing, coefficient of friction and wear resistance are related to penetration depth and residual depth, respectively. Therefore, the partially crystallized 60NiTi film shows the best tribological performance at the micro/nano-scale. The current work not only highlights the important roles of hardness and H/E in improving the micro/nano-tribological properties but also concludes an efficient and simple method for simultaneously increasing hardness and H/E.

Application of aluminium alloys is increasing in all industries due to its combined properties of low weight, good mechanical resistance, thermal conductivity, electrical conductivity, high strength, and good corrosion resistance. In particular, AA5083-H111 alloys have been successfully used in the maritime sector. Unlike purely surface treatments, cryogenic treatment is an inexpensive one-time process that influences the core properties of the components. Cryogenic treatment has recently been introduced to Al alloys. Although the main mechanisms are still ambiguous, considerable improvements on mechanical properties are well noted. However, the effect of cryogenic treatment on the corrosion of Al alloys is limited.This study investigated the effect of shallow cryogenic treatment (-80 °C) on the corrosion of 5083-H111 aluminium alloy, which is used particularly in the shipbuilding industry. Plates of 6-mm thickness exposed to a 3.5% NaCl environment were evaluated via Brinell hardness measurements, Electrochemical Impedance Spectroscopy (EIS) and surface monitoring methods including atomic force microscopy (AFM) and optical profilometry (OP) applied before and after the effect of cryogenic treatment.Results indicated that the duration time of cryogenic treatment (24 h, 36 h and 48 h) had little effect on changing the hardness values and corrosion response of AA5083-H111 alloy in the 3.5% NaCl environment.

“…When the direct manipulation of raw materials is challenging, surface modification emerges as a robust strategy to enhance both performance and durability, particularly for materials subjected to harsh environments or extreme conditions. To enhance surface properties, various advanced surface modification techniques have been developed, including plasma or gas nitriding [33,34], magnetron sputtering [35], and ion implantation [36].…”

The lack of service lifetime of bearings has become a bottleneck that restricts the performance of aero engines. How to solve or improve this problem is the focus of most surface engineering researchers at present. In this study, plasma immersion ion implantation was conducted; in order to enhance the ion implantation efficiency and improve the wear resistance of 8Cr4Mo4V bearing steel, the dose-rate-enhanced method was adopted during ion implantation. The surface roughness, phase constituents, elemental concentration, hardness, contact angle and wear resistance of samples after ion implantation was determined by atomic force microscopy (AFM), grazing incidence X-ray diffraction (GIXRD), elemental dispersive spectroscopy (EDS), X-ray diffraction, nanoindentation tester, universal friction and wear tester, etc. The results showed that the high-dose-rate method had a significant enhancement influence on ion implantation efficiency. At the dose rate of 2.60 × 1017 ions/cm2·h, the roughness of Ra decreases from 24.8 nm to 10.4 nm, which is decreased by 58.1% for the dose rate of 7.85 × 1017 ions/cm2·h. XRD confirmed that the implanted samples consisted of the Fe(M) and Fe2–3N phase and CrN which depends on the implantation dose rate. Meanwhile, the surface hardness was improved from 11.1 GPa to 16.9 GPa and enlarged the hardened region; more valuably, the surface state of samples via high-dose-rate implantation exhibits hydrophobicity with high roughness which is able to store debris and decrease the abrasive wear during testing; thereby, the wear resistance was greatly enhanced by high-dose-rate plasma immersion ion implantation.
