Surface Integrity when Drilling Nickel-Based Superalloy under MQL Supply
The components being manufactured in aerospace industry must be capable of being utilized for long periods without failure. Thus, the functional behavior of these machined components is greatly dependent upon their surface integrity. The present work compares the performance of palm oil and synthetic ester on surface integrity when drilling of Inconel 718. The results indicate the substantial benefit of MQL by palm oil on microhardness, surface roughness, surface defects and sub-surface deformation.
