“…A martensitic microstructure more acicular can be associated with a higher tetragonality of martensite, which is related to the higher carbon content in solution. Jermolajev et al 11 observed, through X-Ray diffraction analysis, that matensite tetragonality increases considerably in rehardened regions, so regions that have undergone superficial alterations in the microstructure during grinding process, which is in agreement with the observations made by SEM analysis of the samples, revealing a martensitic microstructure more acicular after grinding. Figure 7 shows the values of Microhardness x Depth of the samples submitted to grinding in different conditions of cooling, and the sample without grinding.…”

Surface integrity has significant effect on service performance of a component. The surface integrity of workpieces submitted to grinding process depends on the conditions of cooling produced by cutting fluids, which are used to avoid microstructural damage in the process. However, cutting fluids are harmful to the environment and human health, and appear as a crucial element to the optimization of the manufacturing process. In this scenario, biodegradable cutting fluids, such as formulations based on vegetable oils, appear as promising possibility to a cleaner production in grinding process. This study analyzed the surface integrity of AISI 4340 steel, quenched and tempered, in the external cylindrical plunge grinding process with the use of six different formulations of biodegradable cutting fluids (with oils of soybeans, corn, and mineral oil, pure and with additives). The performance of the application of cutting fluids was evaluated by characterizing the microstructure by Scanning Electron Microscopy -SEM and microhardness and roughness measurements. The results showed that the surface integrity of the components was not significantly damaged, which proves the efficiency of biodegradable cutting fluids and feasibility of its use in grinding process.

“…The grinding process involves the contact of the workpiece surface and the irregular abrasive grains scattered on the grinding wheel 8,11,12 . This interaction, in addition with the high grinding speeds involved, causes temperature rise at the workpiece/wheel interface, which may compromise the surface microstructure of the components.…”

“…Similarly, Kalita, Malshe presented that the nano‐particle MQL grinding produces significant reduction of the tangential grinding force and frictional coefficients . This highly desired reduction of the grinding forces has been attributed to the creation of a thin tribo‐film by pulping of the nanoparticles along the grinding path, thereby resulting to better lubrication performance. The thin tribo‐film was found to be created as a result of pulverization of the nanoparticles, which produces facilitates smoother sliding actions between the diamond grains and the work material.…”

“…Moreover, the increase in the lubrication activity also lead to significant reductions of the grinding force ratio . Investigations by Molaie, Akbari revealed that the use of 6% weight concentration of molybdenum disulphide (MoS 2 ) in paraffin as lubricant during grinding operations results in about 25% reduction of the normal force and more than 50% reduction of the tangential force. Similarly, Kalita, Malshe presented that the nano‐particle MQL grinding produces significant reduction of the tangential grinding force and frictional coefficients .…”

“…Studies have shown that the surface quality of mechanical components affects their reliability and performances.Studies have also shown that the use of MQL nano lubrication improves the surface quality of the work piece . The performance of the 2% percent weight of carbon nanotubes as nanofluid on the surface quality during grinding of alumina ceramic was compared with mineral oil‐based conventional coolant.…”

The use of nanofluid in lubrication during machining of advanced engineering ceramics has been found to be highly efficient and eco-friendly. This work involves experimental investigation of grinding Alumina (Al 2 O 3 ) ceramic to determine the effect of the grinding variables. The grinding variables considered include depth of cut, feed rate, type of diamond wheel, and lubrication type. Moreover, the response parameters considered include grinding power, coefficient of friction, and surface quality. The responses obtained during the experiments were used to develop a fuzzy logic prediction model. The findings from this work can be concluded as follows: (a) The depth of cut and feed rate have direct proportional relationship with the grinding power and coefficient of friction. (b) The metallic bonded diamond wheel was found to have higher machining efficiency than the resinoid bonded one. (c) Higher number of diamond grits produces lower frictional coefficient. (d) The carbon nanotube based nanofluid when used in the minimum quantity lubrication (MQL) process proffers better lubrication capability than conventional flood cooling system. (e) The developed fuzzy logic models were found to have high prediction accuracies of 97.22%, 98.60%, and 96.8%, respectively, for grinding power, grinding force ratio, and surface roughness.

In previous years, nanolubricants have gained attention in terms of their use as heat transfer fluids in applications such as engine cooling and air conditioning. Carbon-based nanolubricants have attracted great interest due to their superior heat transfer performance. To date, the stability of a carbon-based nanolubricant is crucial if the enhanced properties are to be retained after the fabrication process. In this context, the current research aims to review the stability and thermophysical properties of carbon-based nanolubricants. Recent works on these nanolubricants are summarized herein, including the method of preparation and improvements in their properties. The factors that affect the thermal conductivity and viscosity are also discussed, and finally, the applications of nanolubricants are described. The recent studies of nanolubricants are summarized and opportunities for further improvements in their efficiency are suggested.
