This study investigated the machining based tribological characteristics of TiC rollers during hard turning under sustainable cooling/lubrication conditions. Surface quality, power consumption, tool wear, microstructural changes, microhardness after machining, and SEM-EDX analysis were evaluated under dry, minimum quantity lubrication (MQL), cryogenic and hybrid cryo+MQL environments. Although the surface quality did not meet the expectations in dry cutting, MQL improved slightly than cryo methods. However, the best surface quality, the smallest tool wear and power consumption was obtained in the hybrid cryo+MQL lubrication/cooling method.eninfo:eu-repo/semantics/closedAccessHard turningCryo plus MQLLubrication/coolingTool wearSurface integrityArticle10.1016/j.triboint.2022.1077452-s2.0-85136592895Q1174WOS:000886908500003Q1
