“…In tribocorrosion, mechanical wear is a fatigue process, which can also promote the initiation and expansion of holes. [ 32 ] Therefore, both corrosion and mechanical wear promote faster initiation and expansion of holes in CBPCCs and this results in a decrease in the corrosion resistance of the coatings.…”

In this study, chemically bonded phosphate ceramic coatings (CBPCCs) with different contents of aluminum phosphate (AP) are prepared on stainless steel (AISI 304L). Differential scanning calorimetry, X‐ray diffraction, contact angle test, and a tribocorrosion experiment are carried out to clarify the role of AP in the tribocorrosion performance of CBPCCs. The results show that, with the increase in the AP content, the enthalpy of curing increases because of the greater formation of the bonding phase AlPO4. Both in static corrosion and in tribocorrosion, the corrosion current density of CBPCCs achieves the lowest value when the weight ratio of AP to polytetrafluoroethylene is about 0.78. Additionally, the influence mechanism of AP on tribocorrosion is clarified. AlPO4 from the reaction between AP and Al2O3 has excellent mechanical properties and can enhance the wear resistance of CBPCCs by reducing the mechanical wear and the increased wear due to corrosion. The alumina particles wrapped by AlPO4 can form a dense and smooth surface and change the direction of electrolyte propagation, which leads to the increase in the tribocorrosion resistance of CBPCCs.

“…Thus, based on X-ray diffraction analysis, it can be assumed that an increase in the volume fraction of α-Al 2 O 3 phase in coatings leads to an increase in their wear resistance. This is because α-Al 2 O 3 has a number of features, including low density, relatively high melting point, excellent corrosion and wear resistance, and high strength at high temperatures [33][34][35]. Figure 9 shows the graphs of the friction coefficients of coatings obtained when filling the barrel by 53%, 58%, 63% and 68%.…”

“…In [28] reported that the hardness of the Al 2 O 3 coating obtained increased from 10.87 to 16.33 GPa by reducing the delay time between shots during a detonation explosion from 1 to 0.25 s. In [17] reported that the hardness of the Al 2 O 3 coating increases from 7.86 to 11.08 GPa as the thickness increases from 250 to 1100 µm. In [35] reported that the microhardness of ZrO 2 -Al 2 O 3 -based coatings obtained by air-plasma injection was in the range of 8.06-9.11 GPa. The micro-hardness of the obtained coatings, depending on the filling with gas, was at 53%-20.6 ± 0.3 GPa, 58%-16.3 ± 0.15 GPa, 63%-17.9 ± 0.25 GPa, and at 68%-18.16 ± 0.27 GPa.…”

Al2O3 coatings were applied on the surface of 12Ch18N10T steel by the detonation method at different degrees of filling of the detonation gun. The aim was to study the influence of technological parameters on the formation of the coating’s structure, phase composition and tribological characteristics. The degree of filling the gun with a gas mixture (C2H2/O2) varied from 53% to 68%. X-ray diffraction study showed that the content of α-Al2O3 increases depending on the degree of filling. The results showed that the hardness increases with an increase in the α-Al2O3 phase. When the gun is 53% filled with gas, the Al2O3-based coating has the hardness of 20.56 GPa compared to 58%, 63% and 68% fillings. Tribology tests have shown that the wear rate and friction coefficient of the coating is highly dependent on the degree of filling of the gun.

“…For brevity, this paper mainly focuses on the tribocorrosion behavior of Al alloys in NaCl solutions. Among those relevant studies, the tribocorrosion behavior of Al alloys are often studied due to three types of effects: (1) The material parameters, such as alloy composition [49], fraction of reinforcing particles [50][51][52][53][54][55], and heat treatment [56];…”

Tribocorrosion, a research field that has been evolving for decades, has gained renewed attention in recent years, driven by increased demand for wear- and corrosion-resistant materials from biomedical implants, nuclear power generation, advanced manufacturing, batteries, marine and offshore industries, etc. In the United States, wear and corrosion are estimated to cost nearly USD 300 billion per year. Among various important structural materials, passive metals such as aluminum alloys are most vulnerable to tribocorrosion due to the wear-accelerated corrosion as a result of passive film removal. Thus, designing aluminum alloys with better tribocorrosion performance is of both scientific and practical importance. This article reviews five decades of research on the tribocorrosion of aluminum alloys, from experimental to computational studies. Special focus is placed on two aspects: (1) The effects of alloying and grain size on the fundamental wear, corrosion, and tribocorrosion mechanisms; and (2) Alloy design strategies to improve the tribocorrosion resistance of aluminum alloys. Finally, the paper sheds light on the current challenges faced and outlines a few future research directions in the field of tribocorrosion of aluminum alloys.
