“…The corresponding results can be seen in Figure 17. In PIID technology, the use of carbonaceous precursors (such as methane or acetylene) can produce DLC coatings with a very high hardness (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) and a thickness of up to 2 µm. Compared with other traditional technologies, the method is simpler and the cost is lower [285].…”

Titanium alloy has the advantages of high specific strength, good corrosion resistance, and biocompatibility and is widely used in marine equipment, biomedicine, aerospace, and other fields. However, the application of titanium alloy in special working conditions shows some shortcomings, such as low hardness and poor wear resistance, which seriously affect the long life and safe and reliable service of the structural parts. Tribocorrosion has been one of the research hotspots in the field of tribology in recent years, and it is one of the essential factors affecting the application of passivated metal in corrosive environments. In this work, the characteristics of the marine and human environments and their critical tribological problems are analyzed, and the research connotation of tribocorrosion of titanium alloy is expounded. The research status of surface protection technology for titanium alloy in marine and biological environments is reviewed, and the development direction and trends in surface engineering of titanium alloy are prospected.

“…In this technique, atomized aluminum powder is combined with other raw powders and compressed. In addition, either elemental or master powder forms of alloying elements are included in trace amounts [14,[16][17][18][19]. For decades, the press-and-sinter processing technique has been the standard for fabricating aluminum powder metallurgy (P/M) alloys into lightweight structural components.…”

The objective of this investigation is to enhance the mechanical and tribological properties of aluminum foam composites through the incorporation of cenospheres and a Mg-Sn alloy. Cenospheres, lightweight ceramic microspheres, are integrated as fillers within the metal matrix composites, capitalizing on their high strength-to-weight ratio and buoyancy. The synergistic effect of the Mg-Sn alloy addition is postulated to fortify the composite, augmenting its strength. These lightweight yet robust composites are poised to offer significant benefits in sectors demanding high performance and reduced weight, such as aerospace, automotive, and biomedical engineering. A meticulous examination of density, hardness, friction coefficients, and wear rates was conducted. It was observed that the inclusion of cenospheres precipitated a decrease in density from 2.51 to 2.01 g/cm 3 with a volume fraction increase from 0 to 55%. The introduction of 0.8% Mg-Sn alloy to a blend of 55% cenosphere and 44.2% aluminum resulted in a density increment to 2.14 g/cm 3 . Concurrently, the Vickers hardness exhibited an increase from 37 HV to 53 HV with a rising cenosphere concentration and further escalated to 57 HV upon the addition of the Mg-Sn alloy. Tribological testing revealed that the friction coefficient diminished from 0.293 to 0.235 µ with an escalated cenosphere volume from 25 to 55%. The integration of 0.4% Mg and 0.4% Sn alloy was demonstrated to significantly enhance the friction behavior compared to the pure aluminum and aluminum-cenosphere composites at a 55% volume fraction. The wear rate exhibited a pronounced decrease from 1.957 × 10 -6 to 1.1245 × 10 -6 g/cm under a 10 N load, which correlated with the increasing cenosphere content. This trend persisted under 20 N and 30 N loads, where wear rates diminished with a higher cenosphere volume fraction. The composition comprising 55% cenosphere and 0.8% Mg-Sn alloy manifested the lowest wear rates across varying stress conditions. Compression testing underscored a consistent decrease in compressive strength from 160 MPa to 65 MPa as the cenosphere content rose from 0 to 55%. However, the composite with 55% cenosphere sees a dramatic rise in compressive strength when Mg and Sn are introduced at 0.8 vol.%. Observed changes in density, hardness, friction and wear rates indicate that composite properties can be improved. These composites have the ability to combine mechanical strength with lightweight design, making them attractive for industrial applications.

“…Titanium alloys are used to manufacture numerous components for aircraft engines, airplanes, and helicopters, with a significant portion of the world's titanium production finding applications in the aerospace industry [2]. An important property of titanium alloys is their biocompatibility, which enables their use in the production of medical implants and surgical instruments [3][4][5]. Greater potential for application of titanium alloys in the biomedical industry can be achieved by modifying the chemical composition, replacing toxic components with biocompatible ones [6].…”

This article presents an analysis of the impact of vibratory shot peening on the surface roughness and physical properties of the Ti6Al4V titanium alloy surface layer after milling. The elements of machine parts and structures made of titanium alloys are often exposed to variable loads during operation. Therefore, it is advisable to apply methods that enhance functional properties and increase the durability of interacting components. Increasing the operational durability of such elements can be achieved by vibratory shot peening. Variable amplitudes A = 24; 33; 42; 51; 60 mm and times t = 1; 7; 13; 19; 25 min were applied. It has been demonstrated that it is possible to achieve a threefold reduction in the roughness parameter, Sa = 0.344 µm, compared with milling, Sa = 0.95 µm. An increase in Smr(c) areal material ratio was observed after vibratory shot peening compared with milling. It has been shown that amplitude has a greater impact on the increase in hardening of the surface layer gh compared with time. The highest rate of change in surface roughness and thickness of the hardened layer was achieved at a vibratory shot-peening time of t = 13 min. The greatest thickness of the hardened layer, exceeding 200 µm, was obtained after shot peening with an amplitude of A = 60 mm.
