“…In order to obtain good cutting quality and reduce excessive tool wear, many scholars [13][14][15][16][17] are committed to adopting various types of optimization algorithms to reduce the influence of various interference factors on the surface integrity of products, so as to obtain the best cutting strategy. There are also some scholars [18][19][20] who are committed to studying the influence of different coating tools, different texture tools, and different wear degree tools on the machined surface roughness during hard turning.…”

The surface topography of the workpiece directly affects its service performance. In this study, CLSM and SEM are used to analyze the effects of turning speed, turning feed, and turning depth on the three dimensional topography and surface defects of the machined surface. Amplitude parameters are used to characterize the machined surface topography of hard turning. Twelve groups of single factor experiments are used to analyze the influence of turning parameters on surface topography. Based on analysis of variance (ANOVA) and 15 groups of Box-Behnken Design (BBD), whether cutting parameters have significant influence on arithmetic mean deviation ( Sa) is analyzed. A mathematical statistical model of Sa is established by Response Surface Methodology, and the effectiveness of the model is verified by 10 groups of experiments. By analyzing the research results, it can be concluded that: (1) The consistency of the surface topography of hard turning is good; (2) In the turning feed direction, the surface defects of the machined surface by hard turning include turning grooves, material side flow, adhering chips, and material surface tearing; (3) In hard turning, the most significant factor affecting the three dimensional roughness ( Sa) is the turning feed.

“…Rafihim et al [12] and Bhardwaj B et al [13] proposed that the main parameter influencing the surface morphology of hard turning is turning feed. Some scholars [14,15] focused on tool structure, tool coating and tool texture to explore the optimal machining strategy of hard turning.…”

The precision machining technology of hard turning has always been concerned by scientific research institutions and manufacturing industries. Based on the single factor experiment, the wear of CBN tool, morphology of machined surface, residual stress during hard turning of W6Mo5Cr4V2 are analyzed by scanning electron microscope, ultra depth of field microscope, laser confocal electron microscope and X-ray residual stress instrument. The research results indicate that: (1) Adhesion, oxidation and friction in hard turning are the main causes of tool wear, the most significant turning parameter that affects the wear of CBN tool is turning speed. (2) High machining velocity, small feed and small cutting depth can obtain good machined surface quality. (3) The axial and tangential residual stresses produced by hard turning are mainly compressive stresses. When the turning depth is approximately 0.19mm, the tangential residual compressive stress is transformed into tensile stress.

“…Graphene, as the thinnest two-dimensional nanomaterial known in the world, boasts a two-dimensional network lattice structure formed by single-layer carbon atoms with a sp2 hybridized orbital. It has excellent mechanical, thermal, electrical, and barrier properties and a large specific surface area [ 13 , 14 , 15 , 16 , 17 ]. Previous studies have shown that graphene, thanks to its filling, template, bridging, and drawing effects, can regulate the growth of hydration products and significantly improve the mechanical properties and durability of cement-based materials [ 6 , 18 , 19 ].…”

Due to its excellent mechanical properties and high aspect ratio, graphene can significantly improve the water and chloride ion permeability resistance of cementitious materials. However, few studies have investigated the effect of graphene size on the water and chloride ion permeability resistance of cementitious materials. The main issues are as follows: How do different sizes of graphene affect the water and chloride ion permeability resistance of cement-based materials, and by what means do they affect these properties? To address these issues, in this paper, two different sizes of graphene were used to prepare graphene dispersion, which was then mixed with cement to make graphene-reinforced cement-based materials. The permeability and microstructure of samples were investigated. Results show that the addition of graphene effectively improved both the water and chloride ion permeability resistance of cement-based materials significantly. The SEM (scanning electron microscope) images and XRD (X-ray diffraction) analysis show that the introduction of either type of graphene could effectively regulate the crystal size and morphology of hydration products and reduce the crystal size and the number of needle-like and rod-like hydration products. The main types of hydrated products are calcium hydroxide, ettringite, etc. The template effect of large-size graphene was more obvious, and a large number of regular flower-like cluster hydration products were formed, which made the structure of cement paste more compact and thus significantly improved the resistance to the penetration of water and chloride ions into the matrix of the concrete.
