Cutting fluids are the most effective method to lower the cutting temperature and decrease the cutting tool wear. At the same time, the cutting fluids influence the corrosion resistance property of the machined surface. In this study, chlorinated paraffin (CP), which is a common additive in the cutting fluid, was selected as the research objective to study its corrosion resistance property. The passivation effect of CP with different concentrations on the machined surface of stainless steel was studied. Electrochemical measurements and surface morphology investigation were used to characterize the passivation effect of CP with different concentrations. The test results showed that the corrosion resistance of stainless steel in the cutting fluid was enhanced with the increase in CP additive. This reason is that the charge transfer resistance increases and the corrosion current density decreases with the increase in CP additive. The X-ray photoelectron spectroscopy (XPS) results show that the proportion of metal oxides on the processed surface of the stainless steel sample was increased from 20.4% to 22.0%, 32.9%, 26.6%, and 31.1% after adding 1 mL, 2 mL, 4 mL and 6 mL CP in the cutting fluid with a total volume of 500 mL, respectively. The oxidation reaction between CP and the stainless steel sample resulted in an increase in metal oxides proportion, which prevented the stainless steel sample from corrosion in cutting fluid.

“…In addition, the bio-based nanolubricants were properly formulated to achieve a pH of 9.2 as cutting fluids with pH lower than 7 have the tendency to corrode Fe alloys, while those with pH above 10 may be harmful to humans. It is worth to highlight that the suitable pH value according to International Standard Organisation (ISO) is between 8.0 and 9.5 [25]. Meanwhile, the biodegradable test was conducted for 28 days using the OECD-301D closed bottle test.…”

This study evaluates the effects of new bio-based nanolubricants blend formulation on the machinability improvement during the turning Inconel 718 alloys. Different proportion of coconut oil (CO), sodium dodecylbenzenesulphonate (SDBS), cocoamidopropyl betaine (CAPB) with 0.5% of aluminium oxide (Al 2 O 3 ) nanoparticles were blended according to the mixture-design methodology to form the nanolubricants emulsion. Machining responses of tool wear, surface roughness, cutting power and spindle power were comprehensively assessed. The analyses revealed that a combination of 107.14 g of CO, 22.5 g of SDBS, and 15.36 g of CAPB was an ideal formulation for attaining excellent tribological and machining efficiency in the turning of the aforementioned alloy. Suitability of the formulated bio-based nanolubricants was also confirmed in terms of toxicity, corrosion resistance, and biodegradability.

Corrosion of AA7075-T73 aluminum alloy during machining process was studied. An experimental device was proposed in order to simulate machining procedure. A design of experiments-DOE was used in order to evaluate what process parameter is significant. Some electrochemical tests based on open-circuit potential vs time measurements and potentiodynamic polarization were performed in machining fluid of low and high chloride concentrations. Results from DOE showed that the chloride concentration in machining fluid and the presence or not of a zinc coating on the bench vice jaw material in the machining system, along with the interaction between these both factors are significant. OCP results showed oxide growth with time in low and high chloride concentration machining fluid. Passivity breakdown was only observed in high chloride concentration machining fluid. Best fitted parameters were applied to a large scale aeronautical manufacturing company, achieving 95 % reduction in corrosion appearance on the manufactured parts.
