“…As a natural nanoparticle, attapulgite has excellent development and utilization value due to its unique physicochemical properties and massive reserves and has been widely used in many elds [21]. As a onedimensional natural nanomaterial with a layered chain structure, attapulgite can promote the formation of an excellent anti-friction and anti-wear repair layer on the metal wear surface during the friction process, which makes it has superior application space in the eld of tribology [22][23].…”

Attapulgite rod clay (ATP) powder has been widely studied as a high-quality lubricant additive, but its anti-wear and antifriction mechanism has not been clearly explained. To solve this problem, oil samples with different attapulgite powder contents were prepared in this study, and friction and wear tests were carried out to test the friction coefficient on the surface of the friction pair. Finally, X-ray photoelectron spectroscopy was used to verify the analysis results, and the mechanism of anti-wear and friction reduction of attapulgite powder was revealed fundamentally. The research results show that the reason why the lubricating performance of the oil sample is closely related to the amount of attapulgite powder is the proportion of Al2O3 and Fe2O3 in the friction layer, indicating that the lubricating performance of the oil sample is positively correlated with the proportion of Al2O3 and Fe2O3 in the friction layer.

“…The finite element method has been successfully utilized in the field of cutting process, which provides a basis understanding of tool wear. Currently, tool wear has been simulated from various points of view, Yao Shuqing [2] established a finite element model of ceramic tool in cutting to analyze the influence of the physical properties of materials such as hardness, fracture toughness on tool wear properties. Monaghan [3] established a finite element model of cutting to study the influence of the rake angle on the tool wear.…”

In high speed machining superalloys processes, tool wear is strongly influenced by the cutting temperature and contact stresses. Finite element analysis of machining can be used as a supplementary to the physical experiment, this paper provides investigations in 2D and 3D finite element modeling and simulation of prestressed cutting for GH4169 superalloy, a tool wear model for the specified tool and workpiece pair is developed based on the Usui's wear model, furthermore, tool temperature, wear rate and nodal displacement on the face of tool in prestressed cutting of superalloy is analyzed under various prestress condition and cutting parameters, and Python language is adopted to modify the Abaqus code used to allow tool wear calculation and tool geometry updating. The results of the simulation indicate that the tool wear rate increases with the increase of cutting time, and the influence of the prestress to tool wear in prestressed cutting process of shaft part is unremarkable.
