“…is not reputable. However, microstructural features govern the resultant tribological performance of Zn–Al alloys [ [246] , [247] , [248] , [249] , [250] ]. For example, tribological performance of lower Al content hypo-eutectic Zamak 2 (Zn–4Al–3Cu) and Zamak 3 (Zn–4Al-0.1Cu) alloys were investigated in comparison with Zn alloys containing higher levels of Cu and/or Al [ 246 , 247 ].…”

“…The improvement in wear resistance with increasing Al content in pure Zn at high loads (40–100 N) was attributed to the specific microstructural evolution [ 249 ]. The role of Ag was studied for gravity casting Zn–12Al alloy by Şevik [ 250 ] and the modified alloys (Zn–Al–Ag) exhibited higher wear resistance compared to the base alloy of Zn–12Al. Both wear rate and COF for all applied loads were reduced with increasing Ag content.…”

Biodegradable metals (BMs) gradually degrade in vivo by releasing corrosion products once exposed to the physiological environment in the body. Complete dissolution of biodegradable implants assists tissue healing, with no implant residues in the surrounding tissues. In recent years, three classes of BMs have been extensively investigated, including magnesium (Mg)-based, iron (Fe)-based, and zinc (Zn)-based BMs. Among these three BMs, Mg-based materials have undergone the most clinical trials. However, Mg-based BMs generally exhibit faster degradation rates, which may not match the healing periods for bone tissue, whereas Fe-based BMs exhibit slower and less complete in vivo degradation. Zn-based BMs are now considered a new class of BMs due to their intermediate degradation rates, which fall between those of Mg-based BMs and Fe-based BMs, thus requiring extensive research to validate their suitability for biomedical applications. In the present study, recent research and development on Zn-based BMs are reviewed in conjunction with discussion of their advantages and limitations in relation to existing BMs. The underlying roles of alloy composition, microstructure, and processing technique on the mechanical and corrosion properties of Zn-based BMs are also discussed.

“…It was found that Pb and Cd elements are beneficial for wear resistance, especially at high loads (30-45 N) while Sn lead to poor wear behavior in comparison with the base material (ZA-8). Strengthening of ZA12 alloy by silver addition is reported to be beneficial for wear properties [53].…”

According to market data, about 15% of world zinc consumption is devoted to the production of zinc-base alloys that are used for manufacturing automotive parts, electronic/electrical systems and also, water taps and sanitary fittings, household articles, fashion goods, etc. These alloys are characterized by low melting points and high fluidity that make them suitable for foundry applications. Typically, they are processed by hot chamber high-pressure die-casting where can be cast to thicknesses as low as 0.13 mm. The die-cast zinc alloys possess an attractive combination of mechanical properties, permitting them to be applied in a wide variety of functional applications. However, depending on the alloying elements and purposes, some zinc alloys can be processed also by cold chamber die-casting, gravity, or sand casting as well as spin casting and slush casting. In this paper, a detailed overview of the current knowledge in the relationships between processing, microstructure and mechanical properties of zinc-base alloys will be described. In detail, the evolution of the microstructure, the dimensional stability and aging phenomena are described. Furthermore, a thorough discussion on mechanical properties, as such as hardness, tensile, creep, and wear properties of zinc-base alloys is presented.Metals 2020, 10, 253 2 of 16 melting temperature, resulting in low energy consumption and long die life, combined with high fluidity, that helps in filling complex mold cavities and very thin sections, typically as low as 0.75 mm or even down to 0.13 mm [7]. They show good mechanical properties, including equivalent, or often better, bearing and wear properties than conventional Cu alloys [8,9]. Additionally, they offer good finishing and ability to be easily plated, making them more resistant to corrosion and wear and improving their aesthetic appearance. On the contrary, they suffer from reduction in performance above 80-90 • C [10] and/or after long exposure at room temperature (aging) [11]. For these reasons, they are mainly used for small non-structural components in many fields as such as automotive, hardware, electric/electronic devices, clothes, toys, sports, ornaments, etc. For instance, parts like safety belt blocks, locking mechanisms, wiper motor housings, cylinder locks, some electronic connectors, handles, tap systems, zippers, belt buckles, spring adjuster in bikes, costume jewelry, appliances, etc. are made from zinc-base alloys (Figure 1).
