Abstract EN
AISI 52100 hardened bearing steel is popular in many industrial applications due to its excellent wear resistance and high strength.
Therefore, a high level of surface integrity of the same is the utmost important requirement to enhance fatigue life.
Machining of hardened AISI 52100 steel is difficult because severe plastic deformation and generation of high temperature alter the surface metallurgy of the machined component and hamper the tool life.
The present investigation includes a comparative analysis of surface integrity of AISI 52100 bearing steel during hard turning under different near-dry environments, namely, dry, Minimum Quantity Cooling and Lubrication (MQCL), Compressed Chilled Air by Vortex Tube (CCAVT), and Hybrid Nanofluid Minimum Quantity Cooling and Lubrication (Hybrid NF-MQCL).
Soyabean (a vegetable) oil is used as cutting fluid in MQCL and base fluid in Hybrid NF-MQCL environments.
To prepare hybrid nanofluid, two different nanoparticles Al2O3 and MWCNT, are used.
The chilled air is generated through a vortex tube.
The surface integrity of AISI 52100 steel was studied in terms of microhardness, the thickness of the white layer, surface roughness (Ra), and residual stresses.
Higher cutting speed and feed show positive and negative correlation on surface integrity of AISI 52100 steel, respectively.
Hybrid nanofluid MQCL exhibits the lowest surface roughness (0.34 μm), microhardness (625 Hv0.1), compressive residual stresses (−168 MPa), and thin white layer (0.9 μm) in contrast, and dry machining shows higher surface roughness, microhardness, tensile residual stress, and thick white layer.
In comparison, MQCL and CCAVT are found to be intermediate.
It is found that hybrid nanofluid MQCL enhances the overall performance of the machined surface as compared to other near-dry techniques.
