“…In order to overcome their inherent insufficiencies, multitudinous successful studies involving surface modification technologies have been investigated to effectively enhance the surface properties of titanium alloys and meet the lightweight structure requirements [7,8]. At present, due to the limitations of physical properties and chemical stability of titanium alloy, the modification means of direct irradiation have no predominance, such as electron beam and ion beam [9][10][11]. In contrast, fabricating metal protective coatings on the surface can be an effective strengthening method, including chemical/physical vapor deposition [12,13], plasma spraying [14,15], and laser cladding [16,17].…”

It remains a popular question whether rare earth oxides encourage reinforcing phases to the uniform distribution in cermet coating to improve the mechanical properties. This study applied laser cladding to prepare the TiAl/WC/CeO2 MMC cermet coatings on the TC21 alloy substrate. The effects of CeO2 content on the phase composition, microstructure formation, evolution mechanism, and properties of cermet coatings were investigated. Results show that the incorporation of CeO2 did not change the phase of composite coating, but the shape of the TiC phase has a close relation to the CeO2 content. CeO2 enhanced the fluidity of the molten pool, which further encouraged the TiC/Ti2AlC core-shell reinforcement phase. With the increase in CeO2 content, the optimized coating contributed to homogenous microstructure distribution and fine grain size. Owing to the hard phases strengthening and dispersion strengthening effects of CeO2, the microhardness of the composite coatings was all significantly higher (almost 1.6 times) than that of the substrate. Importantly, the addition of CeO2 significantly improved the wear resistance of the composite coating. This work provides a certain reference value for the study of surface strengthening of key parts in the aerospace field.

“…The emergence of surface patterns by ion beam irradiation (IBI) techniques is known to occur on a variety of materials including semiconductors [1][2][3], metals [4,5], and insulators [6][7][8], under a wide range of experimental conditions. Since its discovery by Cunningham et al [9] and Návez et al [10], this nano structuring process has drawn attention due to its potential uses in the surface functionalization of materials for applications in microfluidics [11,12], orthopedic implants [13][14][15], and solar cell manufacturing [16][17][18]. As a result, IBI techniques can modify the top surface layers of materials triggering the formation of patterns over large surface areas (few cm 2 ).…”

Surface pattern formation on soda-lime silica glass by 1 MeV Si ion irradiation impinging at an angle of 70o with respect to the surface normal has been studied. Modification of surfaces were analyzed for total ion fluences applied between 1×10^17 up to 4×10^17 ions/cm2. The surface morphology and topography were studied by scanning electron microscopy (SEM), and atomic force microscopy (AFM). These surface techniques enabled the determination of roughness, characteristic wavelengths, and correlation lengths. In addition, electron dispersive spectroscopy (EDS) scans were applied on the surface topography to study the variation of the Si content on the obtained surface patterns. From the measurement of these variables, linear and non-linear regimes were established. At linear regime, the surface morphology develops from an initial flat surface giving rise to ripples for fluences up to 1.4×10^17 ions/cm2. As the ion bombardment continues surface evolve into wrinkles finalizing at cellular-like structures, growing under an anomalous scaling process. The EDS scans indicate the presence of shadowing effects. The morphological changes observed can be explained in terms of a combination of thermal mass diffusion and geometrical factors during ion irradiation, including shadowing and subsequent (secondary) surface erosion effects adapted to few MeV energies.

In recent years, the requirements for high-quality development in the manufacturing industry and extreme application conditions have increasingly demanded higher equipment performance. The surface and interface condition of components is directly related to the stability, reliability and service life of equipment. The development of high-performance or multi-performance surface texturing is of great significance for the effective improvement of mechanical properties, optical properties, catalytic properties and biological properties of surfaces. This paper summarizes the application of textured surfaces in improving the physical, chemical and biological properties of surfaces; outlines the types of texturing patterns and the design methods; analyzes the main technical methods and their characteristics for the preparation of surface textures in additive manufacturing, subtractive manufacturing and equal material manufacturing; and makes outlooks on texturing surfaces from the aspects of performance enhancement, pattern design and manufacturing technology in combination with the development trend of textured surfaces’ intelligence and digitization.
