Probing the tribology and drilling performance of high performance cutting fluid on Inconel 690 superalloy by minimum quantity lubrication technology

This article uses minimum quantity lubrication technology to replace traditional machining. A mixed nanofluid cutting fluid MNFCF was prepared using base oil, LINN4444 ionic liquid, and nanoparticles as raw materials, and its tribological and drilling properties were studied. In the tribological performance test, the friction coefficient of the mixed nanofluid MNFCF is only 0.13. Compared with the control, the wear amount of MNFCF has decreased by about 75%, indicating that MNFCF has good anti friction and wear performance. Similarly, in the drilling performance test, the drilling test temperature of MNFCF cutting fluid decreased by 36.5% compared to the same. After drilling and testing, there was almost no BUE, BUL, or wear on the surface of the tool, with only a small amount of adhesive observed. The results indicate that MNFCF has good potential in drilling Inconel 690 high-temperature alloy.
