“…The wear width, wear depth and wear rate value of the surface texture with acid corrosion were 439.52 μm, 4.22 μm and 5.38 μm 3 /s, respectively. It can be seen that the initial sample surface has highest wear amount under oil lubrication condition and the textured surface after corrosion has the lowest amount of surface wear (Wang et al , 2023; Li et al , 2023).…”

“…However, the textured samples after corrosion in hydrochloric acid solution obtain a relatively uniform and complete textured morphology. The better textured morphology can reduce the interfacial contact area and improve the friction coefficient and wear amount at the contact interface (Wang et al , 2023; Li et al , 2023). Under oil lubrication conditions, the textured sample surface obtains a better texture morphology after corrosion, which results in a more adequate storage distribution of lubricant at the textured interface.…”

“…It has been gained more and more attention in recent years (Chen et al , 2021; Wahab et al , 2016; Costa and Hutchings, 2015). Numerous studies have shown that surface texturing techniques can improve the wear resistance, lubricity, corrosion resistance and other properties of materials, which extend their service life (Wang et al , 2023; Söderfjäll and Gachot, 2023).…”

Purpose The purpose of this study is to further improve the performance of surface texture, the chemical polishing method was introduced and the effect of it on the surface morphology and tribological properties of the surface texture was investigated. Design/methodology/approach The surface texture was processed on the surface of 304 stainless steel with laser technology in air medium. Hydrochloric acid solution (pH 2.4 ± 0.05) was selected and used to soak the prepared texture samples for 12 h. The surface morphology and elemental content of the samples were measured with the white light interferometry, SEM and EDS. To obtain the effect of acid corrosion on the tribological properties of textured surfaces, the samples were tested under dry friction and oil lubrication conditions. Findings The detailed study shows that the melt and burr of surface texture produced with laser processing was reduced due to the corrosion effect of hydrochloric acid. Therefore, the better interfacial tribological properties was obtained due to the improvement of surface-textured morphology. Originality/value The main contribution of this work is to provide a new reference for improving surface texture quality. It also lays a foundation for improving the tribological properties of the textured interface.

“…This is due to the non-addition of Fe-base amorphous Al-12Si hardness is low, wear faster; Adding Fe-base amorphous sample hardness is high, slow wear, bionic micro-weaving structure is not easy to fail, so a longer period of time for the sample to provide a stable lubrication environment, and at the same time, the lubricant stored in the pit of the bionic micro-weaving structure to share some of the load, the pressure of the load on the surface of the sample through the lubricant to the bionic microweaving structure, increase the friction reduction performance. At the same time, the load pressure acting on the sample surface is transferred to the inner wall of the bionic microstructure through the lubricant, which increases the surface area of the sample to bear the load [30], and when the high-speed load passes through the lubricant pits, it creates an additional hydrodynamic lubrication effect [31], which signi cantly improves the friction reduction performance of the material.…”

The objective of this study is to enhance the friction properties of piston materials under high temperatures. To achieve this, we developed a novel piston composite material (Fe-amorphous/Al-12Si) by incorporating Fe-amorphous. Additionally, we employed bionic micro-textured laser surface treatment technology to improve its wear resistance. The influence of Fe-amorphous content on the frictional properties of the composite material was investigated, together with the synergistic mechanism of Fe-amorphous addition and biomimetic texture on Al-12Si under the lubrication conditions of B30 biodiesel diluted engine oil. The results indicate that the frictional properties of the untextured surface of the Fe-amorphous/Al-12Si composite material depend primarily on the amount of Fe-amorphous added. The 10 wt% Fe-amorphous/Al-12Si composite exhibits a dense, void-free microstructure with optimum anti-friction and anti-wear performance. It is noteworthy that the interaction between the "anchoring effect" caused by the Fe-amorphous addition and the "fluid-dynamic lubrication effect" induced by the biomimetic texture further enhances the high-temperature friction properties of Al-12Si. Therefore, this study provides a novel approach for the development of piston materials for biodiesel engines.
