The dissolved solvent was distilled off under a vacuum. The produced surfactant was re-crystallized from ethanol after being rinsed twice with diethyl ether to get the gemini cationic surfactant (GCS) [21][22][23] .…”

This study aims to prepare mono and gemini nonionic emulsifiers differing in HLB to utilize in formulated metal cutting fluids. Also, the cationic gemini surfactant (GCS) was prepared and applied as a corrosion inhibitor and biocide in the formulations. FT-IR and NMR confirmed the chemical structure of the prepared compounds. Different oil package formulations were prepared by adding different trial concentrations of the additives (emulsifier, corrosion inhibitor, coupling agent, and biocide) to the eco-friendly vegetable oil (castor oil). Standard procedures were performed to assess the stability of the formulated base oil packages. Six Formulas demonstrated the greatest oil stability. Oil in water emulsions with varying formulated oil ratios (5–15 wt%) were prepared. A standard test was carried out to evaluate their performance as emulsion stability. It’s been demonstrated that Formulas II and V produced stable emulsions. The wettability alteration of formulas II and V on different metal surfaces was evaluated. The droplet size of formulated castor oil in water was determined via DLS. Corrosion test and tribological properties were also performed. The findings of this study indicate that Formula V is a good choice as a renewable addition for enhancing a variety of performance characteristics of the water-based cutting fluid.

“…However, machining processing often leads to the generation of excessive heat between the tool and the workpiece. To address this issue and enhance tool life while minimizing thermal deformation of the workpiece, metalworking fluids (MWFS) are commonly used for lubrication and cooling [ 3 ]. Nevertheless, the application of MWFs on high-temperature workpieces tends to result in the production of a large amount of oil mist, which then diffuses within the processing workshop [ 4 ].…”

“…Until now, conventional mineral oil has been considered the most common cutting fluid that is widely used in machinery in either straight form or emulsified with water. Also, petroleum products, which exist in mineral oils, were found to have a notable share in up to 85% of the overall consumed MWFs [1,3]. The main reasons behind that are attributed to the mineral oil's outstanding lubricating characteristics as well as the significant impact of the additives and modifiers used to improve its tribological, cooling, and physicochemical properties [4][5][6].…”

Predicting the tribological behaviour in the secondary shear zone in the metal-cutting processes is considered a significant challenge in contemporary research. This work investigated the frictional performance in the secondary shear zone of a planing process using a modified ball-on-disc open tribometer. The values of the coefficient of friction (COF) were tracked between an AISI4140 + QT disc (chip) and a cemented carbide ball (cutting tool) coated with TiAlN under three contact pressures of 0.5, 1, and 2 GPa at a range of sliding speeds starting from 0.2 m/s to 1.6 m/s. The tests were conducted under both dry and lubricated conditions using three commercial cutting fluids of CSF 35 straight oil, Vasco 6000, and Zubora 67H emulsions. Also, the MWFs were tested for their rheological properties and wettability. The tribometer results validated the same COF trend as that in the actual metal-cutting experiments, particularly at 0.5 and 1 GPa in dry conditions. Moreover, Zubora 67H emulsion is proven to be the optimal choice due to it reducing the COF between the rubbing contacts by up to 78%. Furthermore, it showed the lowest contact angle and viscosity index, revealing its ability to easily penetrate, especially at higher temperatures, within the secondary cutting zone.
