Summary: The primary goal of this article was to analyze the effect of texture on skid resistance. Measurements were made on three different groups of surfaces. The test results showed that the relationship between texture and skid resistance varied depending on the type of surface, with a relatively strong relationship found on reference surfaces but a shallow relationship found on aggregate and asphalt specimens. Further research with a larger sample size is recommended to explore different levels of texture.

Summary: The effect of rotational speed on the friction surfacing of nickel-aluminide reinforced Al-Zn-Mg-Cu alloy matrix composite on commercially pure aluminum was studied. The study found that increasing the rotational speed improved the coating efficiency, but the presence of nickel-aluminide did not significantly affect the coating efficiency.

Summary: This study investigates the microstructure, mechanical, and tribological properties of the AA2024-Al3NiCu composite coating fabricated by the friction surfacing process on the AA2024 substrate. The findings indicated that increasing the mechtrode's nickel concentration from 0 to 3 wt% resulted in changes in the coating's thickness, width, and the size and fraction of precipitates. The strengthening mechanism of the composite coating varied depending on the nickel content.

Summary: This research studied the microstructure, mechanical properties, and tribological properties of AA2024-Al3NiCu composite coating fabricated by friction surfacing. The results showed that adjusting the feeding rate and rotational speed can improve the coating efficiency, and there were no significant microstructural differences in different parts of the coating. Furthermore, applying this coating to the aluminum alloy substrate can enhance its hardness and shear strength while reducing the wear rate.

Summary: This paper investigates the preparation of a high friction surface treatment (HFST) using magnetite (MT) aggregates instead of conventional calcined bauxite (CB) aggregates as microwave absorbers. The deicing properties by microwave heating and long-term skid resistance of HFST with different proportions of CB and MT aggregate were evaluated. The results showed that the electromagnetic characteristics of HFST were greatly enhanced by the addition of MT, leading to higher microwave heating and deicing efficiency. However, the long-term skid resistance of HFST was reduced by the addition of MT.

Summary: This study evaluates the relationship between fiber types and mechanic performance of SMA-13 fiber asphalt mixture using polyester fiber, polypropylene fiber, and lignin fiber. The micro-surface characteristics of fiber and aggregates were studied by SEM and image analysis, and Marshall stability and splitting strength were used to measure the properties of the asphalt mixture. Field tests were conducted to evaluate the skid resistance of high-speed vehicles on the pavement.

Summary: This study investigates the impact of consumable rod axial feeding rate on the microstructure, mechanical properties, and wear resistance of coatings during the friction surfacing process. The interaction of the coating and substrate is examined using a thermomechanical simulation. The results show that increasing the axial feeding rate improves the deposition efficiency and shear stress at the coating/substrate interface, while decreasing interface roughness.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: This study evaluates the skid resistance of runways by analyzing the microtexture and macrotexture of the surface. The research shows that aircraft operations have a significant impact on these characteristics. The results indicate that stone mastic asphalt concrete has better macrotexture compared to dense grade asphalt concrete. Aircraft landing operations reduce skid resistance, especially in terms of macrotexture. However, aircraft behavior at high-speed exits affects microtexture more than macrotexture.

Summary: An orthogonal test was designed to evaluate the skid resistance performance of asphalt pavement under cumulative wheel load and overload. Lab tests were conducted using the Tire pavement Dynamic Friction Analyzer (TDFA) to acquire real-time data of tire-pavement friction coefficient and pavement textures. The results showed that the pavement friction coefficients (COF) increased first and then decreased, while Mean Profile Depth (MPD) values fluctuated significantly. There was also a poor correlation between COF and MPD values. Additionally, the deterioration rate of pavement dynamic friction coefficient was faster and the final value was lower when heavy traffic was applied in the early stage compared to the middle and late stage of wear. The designed orthogonal test demonstrated the significant impact of total traffic volume, occurrence interval, and duration of heavy traffic on the COF value.

Summary: The mechanical and tribological properties of AlCrMoN hard coatings with different Mo contents were investigated. The addition of Mo did not reduce the friction coefficient as expected, but it enhanced the wear resistance at 600 degrees C due to the modification of the tribolayer. The incorporation of molybdenum oxides increased the deformation ability of the tribolayer and formed a Mo-N-O interlayer at the interface, promoting the good adherence of the nanocrystalline tribolayer and preventing further wear.
